Granted, it's not extensive, but I'm sure this topic.....especially if you go into the different reasons behind different types of preferences, would fill pages, perhaps volumes. Even those nagging questions of why we are the way we are with regard to kink might be rendered less "sexual oulaw-ish" and more biologically driven than the more bold of us would like to admit.
The truly adventurous among us, no doubt take a certain pride in being "out there" by sheer will and choice. But what if timidity and boldness were just points on a spinning wheel of genetic chance?
But for me the most interesting section was on how the amygdala might well determine political allegiances. In an age where members of each diametrically opposed "tribe" seem utterly incapable of understanding the other side's point of view, and equally ineffective in changing it, it sounds both reassuring and defeatist to think that there may well be an inescapable imperative involved tied directly to our accidental differences in anatomy. When one considers the long anthropological history behind 'tribalism' and its younger, cultured cousin, 'nationalism', it begins to make depressing sense.
What if, at the end of the day, as bad as we all seem to think "tribalism" is, we learn that it is as inescapable as our imperative to live, eat, or reproduce? Even to deciding which tribe to join? What if we learn that our choices, even the ones that seem so rooted in experience and individuality are all "determined" by factors similar or identical to the ones discussed in the article? What if our "individuality" is accurate only in the mathematical permutations of genetics and environment?
I have been a 'determinist' most of my later adult life, so much of this is not a surprise. But in a political climate that has frustrated me so much with seemingly irreconcilable polarities, I feel somehow less inclined now to argue political points. It had seemed futile for a while.....but now I am faced with evidence that it is not merely emotionally pointless, but biologically impossible. And while aspects of this feel discouraging, there is a peace in it as well.....like coming to grips with mortality (although THAT'S one I'm STILL working on.)
