I have very little to disagree with here, and I somewhat accept your premise that we're being driven to be the thing we're behaving as. I mean, that'd just be "fake it til you make it" in a particularly gross context.
However - I've drank beers (and bad shots, why not) around exactly the kinda folks you'd expect to find in some of the diviest bars in parts of rural America that barely (or don't) have a grocery store. Some of those folks are irredeemable, don't get me wrong. A whole lot of them, though, are truly decent folks who've been completely misled.
That was a work thing that I hated and left behind some years ago, but I know very personally two current Trump voters. If you reduce those 2 people to a ballot, pretty easy to condemn them. If you know them the way I do, it's just blatantly obvious they have no idea who and what they voted for. They were fooled, conned, by a known successful conman. It's really that simple.
Edit: redundancy
