My own analysis:When your post was just the first sentence I was going to request that you first post your own analysis.
Eeeegh. Second sentence. It's kind of looking like you might not understand even if I did reply.
But what the hell. Long story short, all the ones I know who voted for him are a varying combination of:
1. 'Biden's-not-that-different'
2. They're staunchly 'a baby can't defend itself'
3. Strong 'keep your beliefs to yourself and help people who are in need' types who feel aggrieved by a perceived thirty/forty-year assault on their morals/values.
Second question, none of them try to do any of that. Get a 'Trump supporter' in private and talk to them long enough, they'll agree with you he's immoral. The fact that you brought it up is kind of weird: surely you know that not all 'Trump supporters' are cookie-cutter evangelicals frothing at the mouth? Also, you do know the average Bible-thumper doesn't really know 'their' Bible, right?
AKA put that all together and it's the usual 'I'm not voting for him, I'm voting against the other guy'. Their voting their issues, not for Trump.
Their decision to vote for Trump is deeply rooted in various combinations of: their clinging to Cold War era propaganda, politico-religious indoctrination, commitment to a tribalist worldview, emphasis on their own money over the common good, fear of a boogeyman, fear of differentness, racism, and xenophobia.
Summarized: they’re ignorant
As to the reasons given by the ones you know...
1) “Biden is not that different” - then what positives do they see in Trump as the difference maker?
2) “They’re staunchly ‘a baby can’t defend itself’” - part of the politico-religious indoctrination point I made. Beyond that, how do they think a baby/infant/toddler/child provides for itself after it is born? Their placement of money above the common good results in them supporting anti-natalist policy while promoting a pro-natalist stance on abortion.
3) “Keep your beliefs to yourself and help those in need” - only if those beliefs contradict with the ones they have and only if the ones in need meet a certain arbitrary checklist in order to receive said help. Their support of a man that is in direct contrast to this exact point and their inability to see that is telling.
4) The point about squaring his actions and words with their religious beliefs - again, the argument is you saying they’re not ignorant “stupid hicks” and you are defending them by calling them ignorant.
