I had a friend who said there's good in the natural order of people getting old and dying so that their bad ideologies can die with them. I've always appreciated that viewpoint. Unfortunately, I have a brother who still lives at home...and he gets that shit ideology from our parents and shit ideology from Stephen Crowder (and even Alex Jones!) and the like online.
And now, he just models my parents where, even when I try to approach him with understanding and empathy, he refuses to even discuss why we should give a shit about immigrants or anyone else. To mash together two of your points, it's like religion in the 50s...there's entire swaths of the US where it can be dangerous to even believe otherwise because everyone around you has their beliefs so intertwined with beating their enemy (communists/the left/atheism, etc.) that at best, you will lose your family, your friends, all your support networks, and at worst, you'll have the devil beaten out of you if you even entertain leaving.
Really good advice, thank you.
