Book review - Sex, Gender, and Engineering: Harassment at Work and in School

 Amazon Review: Thorough coverage and filled with first-hand accounts - 

This tremendous and comprehensive text breaks down the language and impacts of sexual harassment in a meaningful and digestible fashion. Van Antwerp and Wilson delve into what's known about sexual and gender harassment from the literature and point out where work has yet to be done. The book is widely researched including both academic and workplace data and makes helpful distinctions between the two. For those of us who have not studied this area closely, they describe and modify several classic models including learning transfer, stress, and sexual harassment as it pertains to job satisfaction & its antecedents and impacts. This book is invaluable to me as an at-times college instructor and full-time manager of engineers - the differing landscapes are well characterized.

Finally this work attends to solutions and the future in very practical ways. The authors dig into effective learning transfer strategies, different training methodologies and approaches, and expound on the nature and value of bystander training and activism within the specific context of heavily systemized engineering spaces.

I have come away with discussions and ideas to implement with my team, concepts and training improvements to discuss with site leadership, and a better understanding of the importance of cultivating a culture that engenders solidarity with all workers - even a better understanding of my workplace.

The stress tensor

It's a tricky bit of business--something I (shamefully) never fully understood in graduate school. That always bothered me.

Continuum mechanics is wonderful. There, I said it, and now we can move on.

Ok, so the stress tensor.

It is like a vector, but not really. It's bigger than that. In reality, a scalar (such as temperature) is a zeroth order tensor. It only has a value. You can still have scalar fields (temperatures at given points), but they don't have direction. They just are, in the place where they are.

A vector on the other hand, like wind velocity, has direction and a magnitude (size or length) at some location. Therefore wind velocity can be described as a vector field. At each point you have a direction and magnitude (length) of velocity--speed is the magnitude of the velocity vector (how long it is, regardless of direction). A vector is a first order tensor.

Tensors (they can be anything second order and above), are a bit different. Some say they have two directions, and lack an intuitive sense. I prefer to think of one of the directions as the plane of a cube. As far as physical intuitive relationships go this works, because you can think of each dimension in space (x, y, and z or i, j, and k) as having a vector associated with it. Consider the cube. You can push on the cube on three different sets of opposite faces. Each face has one resultant vector applied (perhaps a force vector), and if the forces are equal and opposite, the resultant force vector on that face is zero.

This idea of tensors is commonly applied by chemical engineers with respect to the stress tensor. It describes an infinitely small fluid element in equilibrium. Think a tiny smidge (cube) of water in a pipe flow--it can be any bit of water (fluid) anywhere.
Components of the Cauchy stress tensor in Cartesian coordinates


The little cube will have forces acting:
normal (perpendicular, like a bottle standing on a table, putting a bit of weight on the table) to its faces (hydrostatic stress terms),
and it may have some forces that act on the sides in parallel directions (picture placing your hand flat on top of a slinky and moving it in a parallel direction to the ground as the bottom remains in place) to the sides / faces (shear stress terms) of the cube.
Uni-axial terms (contribute to Hydrostatic stress): σ11, σ22, and σ33
Hydrostatic stress = (σ11 + σ22 + σ33) / 3 = σh
 {\displaystyle \sigma _{h}=\displaystyle \sum _{i=1}^{n}\rho _{i}gh_{i}}
Shear stress terms: σ12, σ13, σ21, σ23, σ31, and σ32

Stress terms in the full tensor, using matrix notation:
{\boldsymbol  {\sigma }}=\left[{{\begin{matrix}\sigma _{{11}}&\sigma _{{12}}&\sigma _{{13}}\\\sigma _{{21}}&\sigma _{{22}}&\sigma _{{23}}\\\sigma _{{31}}&\sigma _{{32}}&\sigma _{{33}}\\\end{matrix}}}\right]\equiv \left[{{\begin{matrix}\sigma _{{xx}}&\sigma _{{xy}}&\sigma _{{xz}}\\\sigma _{{yx}}&\sigma _{{yy}}&\sigma _{{yz}}\\\sigma _{{zx}}&\sigma _{{zy}}&\sigma _{{zz}}\\\end{matrix}}}\right]\equiv \left[{{\begin{matrix}\sigma _{x}&\tau _{{xy}}&\tau _{{xz}}\\\tau _{{yx}}&\sigma _{y}&\tau _{{yz}}\\\tau _{{zx}}&\tau _{{zy}}&\sigma _{z}\\\end{matrix}}}\right]

Hydrostatic stress is isotropic, meaning that it acts the same way in all directions.
{\displaystyle \sigma _{h}\cdot I_{3}=\sigma _{h}\left[{\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}}\right]=\left[{\begin{array}{ccc}\sigma _{h}&0&0\\0&\sigma _{h}&0\\0&0&\sigma _{h}\end{array}}\right]}

Under the conservation of angular momentum the moments (with respect to an arbitrary point) from the stresses on the faces must balance, and it becomes clear that the tensor must be symmetric:
{\displaystyle {\begin{aligned}M_{O}&=\int _{S}(\mathbf {r} \times \mathbf {T} )dS+\int _{V}(\mathbf {r} \times \mathbf {F} )dV=0\\0&=\int _{S}\varepsilon _{ijk}x_{j}T_{k}^{(n)}dS+\int _{V}\varepsilon _{ijk}x_{j}F_{k}dV\\\end{aligned}}}

or in simpler terms:
{\displaystyle \sigma _{12}=\sigma _{21}} AND {\displaystyle \sigma _{23}=\sigma _{32}} AND {\displaystyle \sigma _{13}=\sigma _{31}} OR:
{\displaystyle \sigma _{ij}=\sigma _{ji}}

The stress tensor is a fundamental piece of the Cauchy momentum equation, which relates:
the material derivative, {\displaystyle {\frac {D\mathbf {u} }{Dt}}\ [\mathrm {m/s^{2}} ]}
the divergence of the stress tensor, {\displaystyle \nabla \cdot {\boldsymbol {\sigma }}={\begin{bmatrix}{\dfrac {\partial \sigma _{xx}}{\partial x}}+{\dfrac {\partial \sigma _{yx}}{\partial y}}+{\dfrac {\partial \sigma _{zx}}{\partial z}}\\{\dfrac {\partial \sigma _{xy}}{\partial x}}+{\dfrac {\partial \sigma _{yy}}{\partial y}}+{\dfrac {\partial \sigma _{zy}}{\partial z}}\\{\dfrac {\partial \sigma _{xz}}{\partial x}}+{\dfrac {\partial \sigma _{yz}}{\partial y}}+{\dfrac {\partial \sigma _{zz}}{\partial z}}\\\end{bmatrix}}[\mathrm {Pa/m=kg/m^{2}\cdot s^{2}} ]}
density at a point, {\displaystyle \rho \ [\mathrm {kg/m^{3}} ]}
and the accelerations caused by body forces (gravitational acceleration mostly), {\displaystyle \mathbf {f} ={\begin{bmatrix}f_{x}\\f_{y}\\f_{z}\end{bmatrix}}\ [\mathrm {m/s^{2}} ]}

So all put together, a form of the Cauchy Momentum equation:
{\displaystyle {\frac {D\mathbf {u} }{Dt}}={\frac {1}{\rho }}\nabla \cdot {\boldsymbol {\sigma }}+\mathbf {f} }
[further explanations of these terms below]

This describes momentum transport in any continuum (not just fluids), and from the Cauchy Momentum equation, the Navier-Stokes equations can be derived. The N-S equations describe the motion of viscous fluids in continuum mechanics. These equations are fundamental to the field of fluid mechanics (and are of mathematical interest).

Navier-Stokes equations (incompressible form):
{\displaystyle \overbrace {\underbrace {\frac {\partial \mathbf {u} }{\partial t}} _{\begin{smallmatrix}{\text{Variation}}\end{smallmatrix}}+\underbrace {(\mathbf {u} \cdot \nabla )\mathbf {u} } _{\begin{smallmatrix}{\text{Convection}}\end{smallmatrix}}} ^{\text{Inertia (per volume)}}\overbrace {-\underbrace {\nu \,\nabla ^{2}\mathbf {u} } _{\text{Diffusion}}=\underbrace {-\nabla w} _{\begin{smallmatrix}{\text{Internal}}\\{\text{source}}\end{smallmatrix}}} ^{\text{Divergence of stress}}+\underbrace {\mathbf {g} } _{\begin{smallmatrix}{\text{External}}\\{\text{source}}\end{smallmatrix}}.}

This form has been simplified for use with incompressible fluids (like water), and for a Newtonian fluid (fluid with shear stress directly proportional to fluid velocity) like water the diffusion term describes the 'diffusion of momentum' through the fluid. And if the 'external source' describes a conservative field, the internal source (thermodynamic 'specific' work) can be combined with the external source to give hydraulic head pressure, or just the fluid pressure:
{\displaystyle {\frac {\partial \mathbf {u} }{\partial t}}+(\mathbf {u} \cdot \nabla )\mathbf {u} -\nu \,\nabla ^{2}\mathbf {u} =-\nabla h.}

What about the stress tensor? Where is it? From the Cauchy Momentum equation, the stress tensor disappears but yields a direct relationship, through fluid viscosity μ, to the rate of change of velocity in each direction, which is a useful and easily measurable / observable quantity in fluid motion:
\tau =\mu {\frac  {\partial u}{\partial y}},

Wikipedia has an excellent description of this constitutive equation:


That's pretty much the point of the stress tensor. It's a very useful concept that under-girds many significant and practical calculations in myriad fields of mechanics from weather models, to fluid mechanical models, to physics engines used in video games.

Descriptions of pieces of the Cauchy Momentum equation
[Material derivative]: describes the rate of change of the velocity field (local velocity of the fluid) in time and space: {\displaystyle \partial _{t}\mathbf {u} +\mathbf {u} \cdot \nabla \mathbf {u} }

[divergence of the stress tensor]: describes how the force per unit volume (dimensions and units: 'Pressure / length' SI units are Pa / m = (N / m^2) /m = N / m^3 which gives dimensions 'Force / volume' equivalence) is related to how the stress tensor components change with each direction. This is essentially telling you how the force on a face (per unit volume) is related to how much the stress components on each face are changing in the direction they act.

Why Calvin?

I was 18.

My dad said something like "you should go to Calvin. I would like it if you went to Calvin, and we will help you."

Calvin College had a chemical engineering program, and at the time I told people that I wanted to study engineering at a Christian college. I told them that. I probably thought it. Probably.

I definitely went to Calvin because it offered chemical engineering, and I probably went because it was a Christian college--I grew up in a Christian community you see.

At this moment [actually a few years ago now], Calvin College is conducting Vision 2029. Vision 2029 is a college-wide program and forum aimed at asking good questions regarding the role and trajectory that Calvin will adopt.

Today I attended the panel discussion: “Will Calvin be a Comprehensive Liberal Arts College or a Liberal Arts University?”

Question that arose were "why Calvin?" and "what makes Calvin distinctive?" and "what are our non-negotiables?" with the required (and hopefully not overlooked) subtext: "what are the preceding for an 18 year old?"

I don't pretend to speak for the rest of 18 year olds in the history of 18 year olds considering Calvin, but for my part, that list contained three items:

1. chemical engineering*
2. attractive (reformed) women**
3. residence in the Christian bubble***

*Ok. Yes. Still very pleased about this one
**"The basis of optimism is sheer terror" --Oscar Wilde
***Not the desire for growth in my faith or a deep connection with Christ--more of a cultural imperative

Fortunately for me, I did attend Calvin despite a less than impressive (and retrospectively embarrassing) rationale.

There are many reasons I count myself fortunate for attending Calvin despite being an idiot 18 year old (many would say still an idiot 28 year old [I wrote this in the fall of 2017 and now return to publish it]). I value:

the paper I wrote (truly, truly) poorly analyzing Biblical themes in the 'Russian Primary Chronicle' for History of the West and the World I,

the physics seminars I attended to earn honors credit, and for which I wrote an insipid description of gravitational lenses in Introductory Physics: Mechanics and Gravity,

the immediate, thoughtful (and truly mind-blowing) criticism of the Bible, and exposure to a diverse body of scholarship and views regarding who Jesus was, as a first-semester freshman taking Biblical Literature and Theology,

attacking (engaging really) secular and Christian philosophy directly, with abandon, and without fear in Fundamental Questions in Philosophy with a man who gave us students dignity and the best example of a Christian intellectual I ever met,

an international internship which had me training, training, and planing about Europe and learning sophisticated industrial organic chemistry development in a foreign language (driving my eventual pursuit of graduate study),

and

a broad, functional knowledge of not just my own discipline of chemical engineering, but the ability to speak and work intelligently and effectively with other engineers and scientists in different fields.

As a senior in high school, I question that any of these would have thrilled me as they do now, even if I could now posit their existence to a past self. I recognize them now, after completing graduate study, and taking up teaching.

I certainly would not have relished the thought that, most importantly, Calvin prepared me well to lose my faith in graduate school. For that I am grateful--putting together the pieces of a shattered mess has given my resurrected faith a life it never had.

Vision 2029 will fail if it only addresses "why Calvin" and "what are our non-negotiables" for parents of prospective students that want them to come here. I believe that everyone will agree with me on that point, but to me it bears crying from the rooftops and not treating as a polite, obvious observation. Calvin was truly transformative for me in the most dramatic way after I left.

However it wasn't transformative in any of the ways I would have wanted it to be, or expected it to be as a prospective student.

We cannot foist perspective onto students, we can only give them the opportunities to earn it themselves--that begins with their introduction to Calvin as high school seniors. I wonder if it will take walking a line between humble self-promotion, and vulnerability rendered salient.

[2020 perspective]
The move to 'university' has been completed. Let's add ", or just calling ourselves a university." to the last sentence.
I just read a flowery and not particularly substantive vision of the university structure written for the internal Calvin community, and all it did was to confirm my bias against an ever expanding corps of college administrators projecting a disconnected vision. The questions posited in the aforementioned panel appear to be foregone conclusions looking back. I still value Calvin and the place it is, but I've been struck lately by a lot of self-congratulation and lip service paid, when simply creating relationships between departments and companies, organizations, etc. doing similar work (as an alternative to saying) pays the real bills to establish community and inclusion and brings value to students.

Genetic recombination & 23andMe

Today (when I started this post many months ago) I compared the results of my genetic sequencing with my parents (predictable to be honest). We share a lot--and my parents share none between the two of them.

I'll be transparent. Much of what I learned in 10th grade biology was beyond my ability to apply practically here, and despite doing significant work in mechanobiology and TA'ing a biomolecular engineering class in grad school I was floundering trying to come up with an explanation for completely identical, half identical, and nonidentical segments.

The completely identical and nonidentical were simple concepts. If you compare with a sibling, then the genetic material you received from your parents is the same on both "halves" of the chromosome for identical segments. Nonidentical segments are when neither of the chromosome halves match up.

I highly recommend this post from Barry Starr at Stanford (Ask A Geneticist). He actually explains what most articles fail to address on a meaningful level.

My goal is to briefly recap Barry's explanation, and expound on the possibilities.

Let's start with two parents:
                                                 Mom                                       Dad
They each have genetic code inherited from their parents. We'll identify genetic material in their offspring as coming from a particular chromosome using these colors. On the left, is a chromosome pair of one parent (yellow & orange), and on the right is a chromosome of the other parent (blue & red).

These parents have two children:
                                            Kid A                                             Kid B
Each child inherits material from one parent on one half of the chromosome, and material from the other parent on the other half.

If you consider Kid A, the left chromosome of the pair comes completely from dad, so that whole segment is "half identical" with dad. The right chromosome of Kid A's pair is "half identical" with mom because it contains genetic material entirely from mom.

Ok, now let's compare the siblings to each other.

The following segments are "completely identical" between the two kids:
                                             Kid A                                          Kid B
In the boxes you can see that the colors of each pair match--this is a segment that is "completely identical" because it contains the exact same genetic material from each parent.

Results from the site 23andMe display full siblings the following way (7 chromosomes shown):
Consider chromosome #2 above. The purple color refers to the boxed portion of our siblings above--this part of the chromosome is shared identically by both siblings.
There are large segments in purple, but there is significantly more in the pink color. Pink is referring to "half identical" segments.

The following segments are "half identical" between the two kids:
                                              Kid A                                         Kid B
In the top box the kids share DNA from Dad (red), in the second box the kids share DNA from mom (yellow), in the third box the kids share DNA from Dad (blue), in the fourth box the kids share DNA from data (blue), and in the fifth box the kids share DNA from mom (orange). In each case, the second non-matching chromosome in the pair still contains genetic material from the other parent, but it comes from a different half of the parent's chromosome compared to their sibling.


That leaves "nonidentical" segments. In the 23andMe manner of displaying the comparison it's represented with light grey lines.

The following segments are "nonidentical between the two kids:
                                              Kid A                                         Kid B
None of the boxed segments have the same DNA between the two kids (though if you look closely you can see that I goofed a smidge, and the yellow/orange transition in the middle box doesn't line up perfectly).

Ok, so hopefully the terms are more meaningful, but what of incidence?

Let's isolate small segment and look at the possibilities.

The left half of each chromosome can come from either of Dad's pair, and the right half of each can come from either of Mom's pair, so each of the four above can have two possibilities--this means there are 2 × 2 × 2 × 2 = 16 possibilities.

Let's attribute them all among the three categories:

Completely identical (four)
Red Yellow Red Yellow
Blue Yellow Blue Yellow
Red Orange Red Orange
Blue Orange Blue Orange

Half identical (eight)
Red Yellow Red Orange
Red Orange Red Yellow
Blue Yellow Blue Orange
Blue Orange Blue Yellow
Blue Yellow Red Yellow
Blue Orange Red Orange
Red Yellow Blue Yellow
Red Orange Blue Orange

Nonidentical (four)
Red Yellow Blue Orange
Red Orange Blue Yellow
Blue Yellow Red Orange
Blue Orange Red Yellow

These give us rough proportions to expect. This is a VERY simplified set of proportions, but they get us in the ballpark.
Keep in mind that you can basically do this with billions of segments if we think of the above diagrams as small numbers of base pairs. According to wikipedia:
The centimorgan is also often used to imply distance along a chromosome, but the number of base pairs it corresponds to varies widely. In the Human genome, the centimorgan is about 1 million base pairs.
Over numbers that large, you're going to get reasonably close to an expected value.

When I compared the ratio of completely identical to half identical segments between my brother and I, sure enough, I got about 0.33. When you take the "completely identical" possibilities and divide by the sum of "half identical" and "completely identical" segments you get 0.33. The reason I do this is because it appears that 23andMe includes "completely identical" in the "half identical" segments portion from how they're counted in the analysis. Both are referred to as "shared."
The following are some of my numbers to show how close it can be to 50%:



Reference the following from the ISOGG wiki:
Neither 23andMe nor Family Tree DNA distinguishes between fully identical regions and half-identical regions when computing the number of shared centiMorgans (cMs). Thus, for example, the shared cM for full-siblings will on average be 75% of the total length of the genome, of which on average 50 percentage points are half-identical and 25 percentage points are fully identical.
**Different companies do the calculations in different ways, using different methods, so results can't be compared directly, unless you go through some work to put the numbers on the same basis.**

If we reconsider our rough proportions from the "16 possibilities" this agrees nicely. The "Completely identical" section is counted twice in the last segment because both "sides" (one from each parent) are the same--see the diagrams from "Completely identical" above.
Notice in my example that (13.1% + 26.1%) x 2 = 78.4%--pretty close to 75%.


All that being said, siblings share about 50% of dna with each other, and about 50% with each parent.

23andMe list a table of average shared DNA by relationship: here.


The International Society of Genetic Genealogy also weighs in (again, more information).

An emphatic no

Will Calvin be a Comprehensive Liberal Arts College or a Liberal Arts University?

This question was being considered at a panel discussion I attended last fall, and questions were being asked as to the questions we should ask when considering such a question. Ha! I know.

In the time between when I started this post and its publication the question has been answered: yes.

I concede that this question is relevant, valuable, and necessary to consider for the health of Calvin as it continues into the 21st century.

As an engineer I scream: "Calvin should not be a Liberal Arts University!!!!*"

*whatever L.A.U. means, and however you define it, which is still being worked out in earnest

Perhaps there is room for compromise: "engineering at Calvin should not be expected to expand into an R1 mode!!!!"

It feels like I'm deflecting from the question at hand, however I think the case of engineering maps reasonably well to the rest of the departments at Calvin.

Our engineering department is great at many things. We have dedicated, knowledgeable teachers who come from diverse industrial and academic backgrounds and disciplines. These women and men care deeply about engineering, love the discipline, and care for the health and edification of their students--faculty at R1 institutions also care deeply about their students, however their primary focus in many cases is facilitating excellent research programs, which is a beneficial yet fundamentally different aspect of education and the academy. The primary focus for Calvin faculty is not on grant applications and research program direction.

It's not about being approachable (the doors to faculty offices at R1's are open to students), but rather has to do with the focus of the faculty. Intention gets you far, but purpose is at the heart of Calvin's devotion to equipping students (recite it with me! with gusto!) to think deeply, to act justly, and to live wholeheartedly as Christ's agents of renewal in the world.

I loved the time I spent in graduate study at an R1 institution. It gave me an enormous appreciation for R1 institutions, and more so for the engineering program at Calvin College.

As a TA in engineering, it was clear that while undergraduate students were to be cared for, research was the focus and the important factor. I have never felt this sentiment at Calvin while as a student, nor while as a member of the teaching staff. We do excellent research here--it remains student-focused.

Calvin is good at letting students do any and all of the things they desire (though it may take a bit of time) because Calvin is hyper-permeable. Debra Rienstra, of the english department, made a great point about permeability in education, and allowing students the option to passionately study engineering and music, for example. This is so easy to do at Calvin--talented students do it often.

Personally I was able to pursue both chemical engineering and chemistry majors (a pairing that dovetails almost too easily) and felt integrated and welcomed in the chemistry department though my degree would ultimately be in engineering. I also personally know many students who have combined music with engineering, or public health, or literature--permeability!

The matter of purposeful student development is of real practical meaning and action to me. I taught at Calvin for a few years now and have found renewed purpose and academic redemption of sorts.

So what does Calvin gain? An excerpt from the official press release:
Le Roy says the rationale for Calvin becoming a university is strong, including Calvin’s strength, breadth, and depth of its academic programs; new opportunities for academic innovation; and the college’s increasing influence with students and higher education partners around the globe. The college also has a large international student population for whom “university” is more visible and better understood than “college.”
Calvin leaders also see the university structure combined with increased collaboration as creating a more prominent platform for the institution to express its mission through opportunities and innovation within and across disciplines, professional programs, and centers and institutes.

“A move to a university with a liberal arts foundation both names what we already do and liberates us to do that work better,” said Kevin den Dulk, political science professor at Calvin College and executive director of the Henry Institute. “I’m especially enthusiastic about using the university structure to expand our global reach, which is already considerable yet has a lot of room to grow.”
The bulk of the argument seems to hinge on recognition from international students. I understand the idea that with declining domestic enrollment, it will be key to bolster international recruitment and admissions. But surely reputation and name recognition go beyond the distinction between 'university' and 'college.' Are we now relying on a prospective student or parent to perk up at reading 'Calvin University' on print material, when 'Calvin College' would have caused them to merely gloss over it and move on? This is a weak premise to hang our hat on. Since I've heard 'international recognition' repeated more than almost any other talking point, I don't think this is a mischaracterization.

I truly don't see what the university structure of colleges versus departments will do to facilitate "increased collaboration" and innovation. Innovation and cross department collaboration have been happening for years: ISRx a project melding biology and chemistry departments, and the various interims and summer programs that unite business, engineering, and german programs are two prominent examples that have paid enormous dividends for the departments in question.

Finally let's consider the professional programs. From the standpoint of engineering, I just don't see where the funding is going to come from to provide for post-baccalaureate educational opportunities. Our engineering building is already at capacity hosting senior design team efforts. Where are the research facilities going to appear from for students to do thesis research on one or two year master of engineering programs? Where is the lab space going to open up for chemistry or biology PhD work? No one is arguing for an immediate ascent to R1 status of course, but I also haven't seen a coherent vision of what Calvin University will mean for the different departments/colleges. Certainly such a vision would not need to be set in stone, but I haven't heard even a whiff of a plan for my department, and that concerns me.

Calvin seems to be doing just fine without a 'university structure.' I truly hope that this choice was not made for feathering caps, and prestige.

We'll see what visions develop.

Civic engagement

After a conversation with friends last week, I decided to take action in a simple, thoughtful way.

We were talking about the cost of education, and the kinds of tax breaks you can expect to receive based on the interest you're paying on student loans--the best you can do is to deduct $2,500 of the money you pay in interest on them. It's not a credit.

And at this point, we're not even talking about the possibility of paying a mortgage if you want to own a house. At least with a house you can deduct all of your interest payments...

That seemed woefully inadequate to me, so I wrote this up in a couple hours on a Friday afternoon. Feel free to peruse, use, wholesale copy, or otherwise, and send to your representative and senators if you feel so inclined. Maybe make a call or visit an office.

I did so this week.

Has anyone else done something similar lately? The benefit of having a madman trying to run the nation is that civic engagement seems up.

I believe...[work in progress]

God exists

-[this is the critical, frustrating point that I will never be able to prove, and will honestly, probably always feel uncertain about]

-if I accept that, then the Bible relates that:

--Jesus is the son of God, who came into time and space

--Jesus sacrificed union/love/relationship with the Father on our behalf in a singular way

--we choose to distance ourselves from God in sin

--the penalty for sin is its fulfillment--separation, probably eternal--practically I don't know what that means

--Jesus gives us life freely

--the kingdom of God is greater than my salvation

--the work of the church is to bring the kingdom of God on earth--this happens in sometime conflicting and inconsistent ways (see the Bible)

-the Bible is the story of God's people (in part descriptive, prescriptive, and corrective)--it's God's word, but it is not the Word, nor is it God

--in the Beatitudes Jesus turns power on its head and shows his kingdom priorities

--Parables of the Kingdom tell us how Jesus thought of what was to come:
---the parable of the weeds says that God acknowledges human suffering and strife before his coming Kingdom
---the parable of the sower says that it is difficult to follow Jesus; it is difficult to have faith even; the Gospel of Jesus produces real change in people
---the parable of the hidden treasure describes the way a person gladly gives up his life and possessions, in a way that may be impossible to understand, in order to gain an even more precious way of life
---the parable of the pearl, in a similar way tells of the value of the Kingdom of heaven--worth more than any current power
---the parable of the growing seed reassures those tasked with Kingdom building that their labor is not in vain--a new thing is growing
---the parable of the mustard seed describes the extent and breadth of the pervasive Kingdom
---the parable of the leaven tells of how the Kingdom of God is inevitable after introduction of yeast--surely the resurrection of Jesus

-Jesus is the best thing for everyone because his resurrection is the preview of God's plan for a kingdom made right

-our fellow man deserve love not because they are objects to be converted, but because they are loved by the creator as much as I am

-faith is mysterious and maddening--sometimes I hate it

Birds eat grass

I'm expectant and bubbling--effervescent and impatient.

The semester is over. I've graded the students; I've graded the course & myself.

Work continues such as it is. Folks & products are heated & cooled. Oil lubricates and is washed away.

But I. I sit on the edge of a precipice.

It might not be a precipice (do my legs stretch before me in the dirt?)--I might be poised above four blades of browning grass.

Or. Or I might be clawing for air: a fledgling.

The idolatry of power

More than anything else, the election in 2016 has been a mirror, showing me what I naïve fool I've been.

I'm going to preface what I say next with three important statements...
I think it is possible to have voted for Donald Trump as a Christian.
I think it is possible to have voted for Hillary Clinton as a Christian.
I think it is possible to have voted for a third party candidate as a Christian.
My naïveté comes from expecting that the white, Christian, evangelical church* would live beyond politics--that is, biblically contextualize them within the Christian life [*note: the CRC is evangelical, a member of the National Association of Evangelicals (NAE)].

I was a fool to think that the Church would be honest with its poorness of spirit and need for the gospel. I was a fool to think Christians would embrace the way Jesus turned human politics on its head. Evangelicals have demanded a modern Saul as their king [1 Samuel 8]. Saul is who they have received.

In past elections the "religious right" have voted for Mitt Romney due to their embrace of family values (likely because they were uncomfortable with the idea of a Mormon in the White House--considered by the CRC to be a cult). Family values means: opposed to rights for LGBTQ citizens and an anti-abortion stance.

Overwhelming support of Donald Trump by evangelicals (81%) is the most recent symptom. It is remarkable, that for so many "liking neither candidate" (a common refrain), they came out in record numbers for a Social Darwinist candidate. This is greater than support for Bush, McCain, or Romney--typical Christian-backed candidates.

I can't take the "liking neither candidate" statement seriously, because the truth is Christians voted for a man that denigrated minorities, women again & again, his fellow GOP hopefuls, the disabled, and military heroes.
Many had no problem calling a professed Methodist evil.
They might have honestly believed that, but I think the real reason is that faith in conservatism and liberalism shone through. Evangelical Christians trusted their parties and political ideology more than they did their Jesus and his message.

Many high-profile Christians did.
Some went as far as Wayne Grudem: "now that Trump has won the GOP nomination, I think voting for Trump is a morally good choice."
Pat Robertson dismissed Trump's comments about grabbing women as "macho talk".
Jerry Falwell Jr. endorsed Trump and said “Five years from now when we’re sitting here and we see all the Constitution being ripped apart by justices (appointed by Clinton), nobody is going to remember what horrible things Donald Trump said over a decade ago,” and in the same convocation, Ralph Reed pointed to abortion as the “defining moral issue of our time,” saying Trump is “running on the most pro-life platform in the history of the Republican Party.”
Franklin Graham has made comments that "the godless progressive agenda of Barack Obama and Hillary Clinton likewise cannot be defended. I am not endorsing any candidates in this election" then goes on to say that the future Supreme Court appointees are the most important issue of the election.
James Dobson is a one issue voter: anti-abortion.

A prominent theologian, Miroslav Volf, did come out for Clinton (with reservations): "The best case to be made for Hillary Clinton is that on balance she better represents the convictions and character that should concern Christian citizens. No candidate is perfect."

Christianity Today polled a very curious number, which seems to explain the shift we saw: evangelicals shedding their concern with moral authority and Christian witness.
Q: Can elected officials behave ethically and fulfill their public duties even if they have committed immoral acts in their personal life?
30% of self-identified white evangelicals said yes in 2011
72% said yes in 2016
To move from 30% to 72% in four years is a remarkable pivot--a pivot that essentially supports conservatism, and an anti-abortion stance as the most important issue facing the world and the church.

Choosing to stake that claim on a candidate like Trump with a precarious position on abortion baffles me.

I understand that many Christians (and Americans in general) feel they weren't being listened to--the Democratic Party did an abysmal job of this: they catered to centrist, elitist, imperialist positions.

1) the Sanders campaign was shoved aside in favor of what party leadership wanted
2) the perspective of middle America (and perhaps evangelical America) was ignored: factory jobs lost due to globalization, facing stagnant wages

Clearly there was a gross failing in the Democratic party to reflect and represent its constituency (I wrote about my distaste for Clinton's position previously). It remains to be seen if the party will recover.

However...the fact that evangelicals are defending Donald Trump, or even happily joining the "Trump Train" still beguiles me. Christians are certainly meant to engage with politics, as citizens building God's kingdom now, but what that looks like allied with Trump is unclear.

As he fills cabinet positions, being praised by the alt-Right (literal neo-Nazis), I don't hear concern from conservative Christians. I don't hear anything at all [note: as of 2:30pm 22Nov16, Trump has disavowed "the alt-Right"].

What I have seen are Christians who I once thought respected me, label non-conservative Christians as "sad" people, and others claim victory for the church with a Trump win.
It's one thing to support a candidate--another entirely to be honest with who they are and the extent to which they deserve support and criticism.

I can't speak for anyone else, but for my own part I want the world to easily identify me as a Christian & kingdom builder, and wonder briefly about my politics. I don't intend to be a modern Sadducee.

I'll leave you with this out-shot to think about, from a post written four years ago in response to the Obama-Romney race:
Pastors will have to ensure congregations know right doctrine—a desperate need for this generation of Christians in any case. Individual Christian voters will need to distinguish, perhaps publicly, between their vote for the politician and their fierce disagreement with that politician's beliefs.

The dark side of Clinton's American exceptionalism

Hillary Clinton is an imperialist and hawk, comfortable with the use of American force abroad.

Though perhaps not as strongly as others, she embraces American exceptionalism, defined either as America's superiority over other nations, or as America's unique ability or charge to change the world.

Great empires the world over have viewed themselves as exceptional--from Imperial China to Britain. That re-purposed narrative rings tired to me. America's foundation and rise in influence are perhaps singular, but to take that as a divine mandate is folly*.

In our nation's history, this view has resulted in such conflicts as Vietnam, Iraq, and Afghanistan.

As Secretary of State, Clinton supported the United States-Colombia Free Trade Agreement--passed by Congress in 2011 and set in motion during President Bush's second term in 2007. Her stance on trade has of course changed over time. In 2008 she opposed it, citing "the history of violence against trade unionists in Colombia," which is turning out to be a very real concern.

The agreement is meant to:
"...expand U.S. goods exports alone by more than $1.1 billion and give key U.S. goods and services duty free access in sectors from manufacturing to agriculture. It will increase U.S. GDP by $2.5 billion and support thousands of additional U.S. jobs."
While it hasn't been covered in great depth by mainstream news sources, Daniel J. Camacho, a scholar at Duke (and Calvin grad) who I follow on Twitter, has been an outspoken critic of the Free Trade Agreement and Clinton's involvement:



In a well-reported piece by the Nation, Michael Norby and Brian Fitzpatrick delve into the internal refugee crisis in rural Colombia, exacerbated by the agreement. The country is one of the most dangerous in the world for union members, with ITUC reporting:
"that thirty-five unionists were murdered in Colombia in 2012, solidifying the country’s status as the most dangerous place on earth to be a union member. Between 3,000 and 4,000 Colombian unionists have been killed since the late 1980s."
Criticism of American exceptionalism is clearly not popular. It's even touted in the first line of the 2016 GOP Platform: "We believe in American exceptionalism."

But that doesn't make it right, and that doesn't make us, as a nation, above reproach.

The reason this hasn't seen more coverage is that both major parties are complicit. The U-CFTA has been a bipartisan effort, passed under the Obama administration, but since it benefits American exports, no one is saying anything.

Clinton deserves criticism on this. We are better than this. If we truly are exceptional, we can show it by engaging in trade agreements that are fair and just to both nations, and that don't leave the poor in a state of dire marginalization and violence.

I'll leave you with one of Daniel's tweets:

*I'm proud to be an American, but to say that we are inherently different from other nations is hubris.

Political correctness or dignity (and whiteness)?

If you listen or read anything remotely related to political matters in the United States (or probably elsewhere), you will have heard the term 'political correctness.'

The trend lately is to decry what is seen as overly politically correct speech, used by candidates or officials.

Recently in an Esquire interview, Clint Eastwood has praised Presidential candidate, Donald Trump and ranted about political correctness:

"Because secretly everybody's getting tired of political correctness, kissing up. That's the kiss-a-- generation we're in right now. We're really in a p---- generation."

"Everybody's walking on eggshells. We see people accusing people of being racist and all kinds of stuff. When I grew up, those things weren't called racist."
I'm not sure who 'everybody' is. More troubling though, I am not sure the use of 'political correctness' isn't meiotic, a stand-in for something more sinister--in this case I'm speaking specifically about race in response to Eastwood's comments, though the implications reverberate broadly (see note at the end).

In a way, push-back against political correctness definitely sounds better than push back against 'the Golden Rule.' The GR, in the words of Jesus (Matthew 7:12):

In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.
I want to be able to tell my own story, in my own terms--allowing that I am honest with myself, most people would agree to this plea because most desire it for themselves (the degree to which you are allowed that chance by others is directly related to how much they trust your version of things).

White people have always been able to frame discussions and terms used to describe White people--historically we've also been free to describe any other race and frame class discussions without fear of repercussion or consequence.


A side note to make this point: consider the picture you have in your mind of 'White people.' I immediately envision a White middle class family with a house and yard in the suburbs--a class specific image that doesn't paint the whole picture. It doesn't describe poor Whites in any number of locales, or the super rich either. The class we each come from and belong to frames the way we generalize about groups. Class provides enormous power when it comes to description--like it or not, the classes with more money (power) are afforded the privilege of enhanced perceived credibility (the same goes for level of education).


Going back to my point about who is allowed to frame discussions and terms: White people. Historically the locus of power has been with White people (slavery & reconstruction via Jim Crow, Native American reservations, Chinese laborer immigration restrictions, Japanese American internment camps) and non-Whites have paid the price (even the term non-White does this! It frames a White-centric perspective.).


The locus of power does not lie merely with martial or political power however. It lies with who is able to control dissemination of communication (look at how Republicans and Democrats have partisan language patterns--it's important!).


Lately you hear talk about how great things used to be. People describe wanting to go back to something that has apparently been changed.


I think I know what's changed. I don't think it's because violent crime is on the rise (it's on the decline) and I don't think it's because people are "race baiting," whatever you think that term means.


I think it's because White people are hearing Black voices (and of other people of color), and they don't like it, and they aren't used to it, and they want it to stop because it makes them uncomfortable (I had the same experience before I thought about why I felt that way). It's likely due to the expansion of social media platforms and coverage of the 24 hour news cycle. Black voices can be unsettling to the concept of whiteness (see reading resources below) particularly when we're used to information that has been sanitized in some way by Whites (how would a White person like it to sound?).


The #BlackLivesMatter movement and Civil Rights movement are prime examples of this.


Let's address the Civil Rights movement. Dr. King's Letter From a Birmingham Jail is a direct response to White clergy who were convinced that the ongoing demonstrations were "unwise and untimely" (let's wait for all the facts, don't be hasty). Black people were demonstrating and resisting and doing their own thing to advance justice. White clergy (and White Christianity) were threatened by this.


Today, when people make the statement that "Black lives matter," they are immediately met with resistance, in the form of "all lives matter"--as if that statement needed to be said. White people don't like the sound of "Black lives matter." It makes us uncomfortable, not because we don't think it's true, but because it is not a White-centric message. Sure, White voices like mine feel comfortable saying it, but many Whites don't feel comfortable hearing it.


A Black voice said it originally, and Black and White voices continue to echo it.


It's like Broderick Greer (an Episcopal priest I follow on Twitter) says repeatedly:


We Whites are used to treating others like WE want them to be treated, with OUR voices.

We Whites are seeing push-back by other groups, increasingly being able to define terms and rescue/create dignity by being called what they want to be called.


Some of the power being given up by Whites via the dismantling of 'whiteness' is the ability to, with comfort, ignore 'the Platinum Rule': treat others like THEY want to be treated. We don't like the loss--it feels like people of color are being overly sensitive, when really they just want the dignity of telling their own story with their own words.

If you want to tell me I'm racist for writing this, here are a couple steps:


1) Read the resources on 'whiteness' below.

2) It's not racist or 'race baiting' to talk about matters of race.
3) If you disagree with the concept of 'whiteness' the burden of proof is on you, because there is significant scholarship to support it.
4) Ok, having done that, describe how I'm racist, and give some support for your argument.
5) Cool. Thanks. I'm racist.

Note: the idea of political correctness or dignity is directly applicable to how different groups frame the discussion around the rights of LGBTQ individuals as well.

I've heard descriptions such as "tranny, he-she, it, shemale, transvestite, man in a dress, hermaphrodite, or freak." Those slurs are meant to strip dignity and wound. There is no other reason for them.
For some, these might not be slurs, but for the people in the video, they are, and they hurt. The point is not which specific words can or can't, should or shouldn't be said, it's about treating people how they want to be treated.

It's a choice to use language that conveys dignity--when you choose to "not be politically correct," know that what you're doing is intentionally stripping dignity from a group or person, nothing more, nothing less.

Even if someone's identity makes you uncomfortable, you can still treat them as a person--you're the only one who needs to come to terms with your discomfort.

They're mostly NSFW lyrically.

In no particular numerical order, except via tiers:

3. Q-Tip and Phife Dawg
4. Rakim

S-
5. Nas

I'll recognize the unquestionable brilliance of others such as Mike Shinoda too. I like Linkin Park and Fort Minor, sue me.

This list brought to you because I just watched Lin-Manuel Miranda do his top 5.

The criterion was personal preference, lyricism, and sound (generally). I concede my taste is confusing, inconsistent, questionably informed, and ordered unconventionally. I'm a fan not a head and I can't speak very intelligently about hip hop but I've had many good recs from my friend Dan Lee and Jesse Thorn (Bullseye).

Hey White People!

Black fathers, mothers, daughters, and sons are being murdered.

The state is essentially sanctioning these lynchings, and you aren't saying much of anything.

What many of you ARE saying is that "all lives matter," or looking for justification for the murders.

The rest of you aren't saying anything at all. You're posting about the fourth of July, or about emails that should have been more secured. Maybe you don't like to "get political."

It's fine to not get political if you're white, because you can afford to. This political cycle won't change much for you. You'll complain about Trump or Clinton for a few years.

Everything is political for black people; they have no choice, because they are dying at the hands of the state. They are dying for no reason, in most cases innocent. In the case of allegations, they are being executed instead of receiving trial.

I'm not choosing to write this because I'm a conservative or a liberal. I'm writing this because people are dying and few of my white friends are saying anything at all. My black friends are saying plenty, but I'm not convinced you're listening.

All lives won't matter until black lives matter, so save that s*** for another day. I chose to use that crass word, because it speaks to the nature of the "all lives matter" statement.

ALM is willful ignorance and white silencing of the devastation and horror that black families feel when their fathers, mothers, sons, and daughters are killed at the hands of those supposed to be protecting them. No one disputes that life matters. It's in our Declaration of Independence. We get it. It's supposed to matter.

I'm not blaming you or myself for hating black people, because most of you DON'T.

I'm not blaming you for anything.

But if you stay silent now, or the next time, or refuse to LISTEN and LEARN and EDUCATE yourselves, you are becoming complicit. Your silence is deafening. And that is worthy of blame.

Conservatism & Liberalism & civility

Liberalism and conservatism are tools.

Each ideology is inherently at odds with the other. They are not moral opposites (rather amoral), but are opposing systems of thought. Let's lay each of them out.

Liberalism, highlighted:

John Locke, the father of liberalism, regarded

     religious tolerance,
[separation of church and state due to the fallibility of man, and the idea that belief cannot be compelled by violence]
     private property,
[a natural right determined by the use of labor to produce goods or property, which PRECEDES government*]
               and

     opposition to the divine right of kings (tyrannical rule),
[the will of the people gives authority to the government]
as important philosophical tenets. These among others, such as liberty and equality, underpin theories of liberalism and the very foundation of the American experiment--they directly inspire the Declaration of Independence and the American Constitution.

Necessarily distinct from broader liberalism, modern American liberalism has generally come in the form of protecting citizens from economic oligarchy, as opposed to monarchy in most of the rest of the world, for obvious reasons (the American Revolution was a liberal event in the context of monarchy). Application of rights to Americans has broadened since 1788/1791 to include poor white men, women, black people, and as of late, LGBT citizens--essentially liberal developments.

Paul Starr, American professor and co-founder of liberal magazine the American Prospect, in 2007:
"Liberalism wagers that a state... can be strong but constrained—strong because constrained.... Rights to education and other requirements for human development and security aim to advance the opportunity and personal dignity of minorities and to promote a creative and productive society. To guarantee those rights, liberals have supported a wider social and economic role for the state, counterbalanced by more robust guarantees of civil liberties and a wider social system of checks and balances anchored in an independent press and pluralistic society."
Generally this agrees with liberalism as politics of liberty and equality--in a matter of speaking:
developing the common good advances the freedom of the individual.

Conservatism, highlighted:

In 1959 Quintin Hogg, chairman of the British Conservative party, wrote in his book The Conservative Case, that:
"Conservatism is not so much a philosophy as an attitude, a constant force, performing a timeless function in the development of a free society, and corresponding to a deep and permanent requirement of human nature itself."
If you take Hogg's statement, the conclusion has to be that this attitude depends precisely on the current state of affairs, to which conservatism is a response. Conservatism is a necessary force, a pull, that helps society determine if the strides we are making are good and merited.

American conservatism is a different entity--one based in historical context and current social forces.

William F. Buckley Jr., American author and conservative voice:
"Among our convictions:
It is the job of centralized government (in peacetime) to protect its citizens' lives, liberty and property. All other activities of government tend to diminish freedom and hamper progress. The growth of government (the dominant social feature of this century) must be fought relentlessly. In this great social conflict of the era, we are, without reservations, on the libertarian side. The profound crisis of our era is, in essence, the conflict between the Social Engineers, who seek to adjust mankind to conform with scientific utopias, and the disciples of Truth, who defend the organic moral order. We believe that truth is neither arrived at nor illuminated by monitoring election results, binding though these are for other purposes, but by other means, including a study of human experience. On this point we are, without reservations, on the conservative side."
Buckley acknowledges that his second and third sentences are remarkably libertarian--then makes an interesting judgment concerning "Social Engineers" meaning liberals, and the conservative "disciples of Truth," defending order. This is the crux of what it means to be conservative in any context.

Current American conservatives sail by the prevailing winds of tax-cuts, increased military spending, family values, deregulation, and smaller government. Much in the same way that modern American liberalism draws from Roosevelt's New Deal and Johnson's Great Society, these Reagan era ideals generally describe what it is to be conservative in America today.

--
Let's go back briefly to what Buckley said in his first sentence. He reminds us that government is meant to "protect its citizens' lives, liberty and property." It's rather a curiously liberal statement, one with which Locke, the father of liberalism would agree.

This reinforces the story of liberalism and conservatism as opposing forces relative to their time. Civilization has come a long way since the 17th century--today, Locke would be surprised at how liberal the conservatives in America tend to be. I don't say that as an insult or a jab. Scholars say the same.
Leo Ribuffo, American historian, in his book Historically Speaking:
"what Americans now call conservatism much of the world calls liberalism or neoliberalism."
What better way to explore this tension than through the politics of Abraham Lincoln, first elected President for the Republican party, a man claimed by both modern Republicans and modern Democrats (for good reason)?

The Lincoln case study:
In 1859, Lincoln regarding conservatism in the United States (pg 35):
"The chief and real purpose of the Republican party is eminently conservative. It proposes nothing save and except to restore this government to its original tone in regard to this element of slavery, and there to maintain it, looking for no further change in reference to it than that which the original framers of the Government themselves expected and looked forward to."
Lincoln hearkens back to the spirit of the Founding Fathers, yet later he issues the Emancipation Proclamation, a profoundly self-contradictory and liberal act.

On one hand, it led to a very progressive expansion of rights for slaves, but on the other, it displayed a carelessness toward the Constitution via Lincoln's assumption of powers ("unilateral decision to call out the militia to suppress the "insurrection," impose a blockade of southern ports, expand the army beyond the limits set by law, spend federal funds without prior congressional authorization, and suspend the writ of habeas corpus" [source]) for which he was heavily criticized by Democrats.

Like the Founding Fathers he was a classic liberal, but not in the sense that we describe liberals today. To do much of what he did, Lincoln needed, and used (though vehemently protested by many) a strong federal government and its powers, yet described himself as a conservative (as defined at the time).

He is neither a modern conservative nor liberal, rather some amalgam.
That amalgam successfully held the Union together, and simultaneously phased out slavery (which the Founding Fathers expected would wane, gradually wither, and die).

You can look at Lincoln as having a sort of internal bipartisanship, a sort of effective cognitive dissonance.

--
Liberalism and conservatism in America have many points of conflict, as well as points of commonality. They are ways for our society to decide how we want to be governed and how we want to BUILD a greater nation.
Yet, often we squabble about politicians being too this or too that; we're concerned less with WHAT we are building, as with WHO is building it and how offended we are by them, or how well they're liked. The Founding Fathers weren't exactly a basket of peaches, but their ideas were effective and visionary--the ideas are the point.

Focus on political identity, unwavering stances, and bombastic speech, rather than movement forward to build a better system, polarizes and paralyzes American politics.
The Economist reported on a chart generated by Renzo Lucioni, a computer science student, that illustrates via similar voting habits, how bipartisanship has eroded in the Senate from 1989 to 2013.
It's not surprising, but it is worrisome.

Pew Research Center has concluded that while a more significant portion of Americans today tend to be consistently liberal or consistently conservative, the groups that comprise the middle are:
"...a combination of groups, each with their own mix of political values, often held just as strongly as those on the left and the right, but just not organized in consistently liberal or conservative terms. Taken together, this “center” looks like it is halfway between the partisan wings. But when disaggregated, it becomes clear that there are many distinct voices in the center, often with as little in common with each other as with those who are on the left and the right."
This would be good news if we had a mixed-member proportional representation like Germany (1949 at inception) or New Zealand (1994 after electoral reform), but with our two party system, there is very little incentive to vote for a smaller party, which means that the smaller parties have very little opportunity to contribute to decision making at any level, much less national or as part of a coalition.
Over time this has led to more polarized identity-politics, and the emergence of groups like the Tea Party which insist on radical commitment to principles that are pseudo-Republican, branding as traitors those who are not conservative enough.

That being said, there isn't a right or wrong party.
Truths**:
1) You can care about science and facts as a conservative or liberal
2) You can be highly educated, and value it, as a conservative or liberal
3) You can care about the plight of the poor as a conservative or liberal
4) You can be the civil opposition as a liberal
5) You can be the civil opposition as a conservative
6) You do not have to hate conservatives to be a liberal
7) You do not have to hate liberals to be a conservative
8) #6 and #7 each bear repeating...
The reality is that we have two political parties and their members in our legislature are tasked with representing a constituency that is often uniformed on subtleties of ideology, and who on both sides sometimes refuse to do the hard work of being informed.
I too am a complicit member of this electorate.

Do we look to members of another party and choose to simply throw cheap shots, mud-sling, character-condemn & -disparage, or do we choose to actually acknowledge the differences and how they can be reconciled or used to compromise, and build a better version of America?

It is SO† much easier to ham-fistedly and self-righteously scream and argue a point (being unwilling to concede an INCH†), than to consider, reconsider with good information, then work toward a solution that honors conservatism and liberalism (or libertarianism) as guiding principles‡.

Please choose to do the latter. It's how America was built.

*Note: Locke however "implies that government would function to moderate the conflict between the unlimited accumulation of property and a more nearly equal distribution of wealth; he does not identify which principles that government should apply to solve this problem." This is a very important point, as we live in an age where political monarchy have been replaced by economic monarchy.
