1 & 2 are probably good pieces of advice, but hard to follow.
3 is at this point verging on obvious. But I don't even want to "argue" with the disillusioned ones let alone those that are still firm MAGA. I want to do bad things to them that I don't feel entirely safe to admit explicitly here.
5 & 6 though... I don't know. Maybe we'll get past this but I'll always have the knowledge that most of my fellow citizens are bad people. That is simply hopeless. There is no escaping that knowledge.
I'm basically going to forever have a potential litmus test for people born before 2007 or so on how to treat them. Asking them who they voted for in 2024. Sure, they can lie but that's fine. If they're ashamed enough to lie then that at least softens my perspective on them a little anyway.
