What you describe can be boiled down to lack of enlightenment. Like, the thing our ancestors fought really hard for in the past 500 years or so (historians please correct me), the very foundation on which things like a stable democracy are build upon.
The USA always had really weak education and overbearing religious tomfoolery, but now it blew up to a damn crusade against everything enlightenment stands for. For the foolish it's "one-upping the libs", for the uneducated or indoctrinated it's "doing gods work", the powerful see it as an opportunity to shift power to their own "rightful" rule. Meanwhile the only thing it actually is is a damn tragedy that leads to suffering and death.
Sorry if my english is somewhat clunky.
I once had someone attack me on Mastodon for the Palestine flag in my profile (next to the Ukraine one), telling me that "those people" would happily kill me too for being trans and whatnot. So I was obviously an indoctrinated idiot.
I still cringe about that selfish ignorance. As if a constant state of war and terror would enable anyone to be more open and progressive. As if a society that successfully eradicates another one would be like that either. It's so phenomenally short-sighted.
At which point does our educational (and healthcare -> therapy) system fail to teach the simple fact that the only way to lasting peace and prosperity is to ensure safety, rights and wellbeing of even those who we may not like or who may not like us? Obviously a lot of people in this world would like to see me dead or incarcerated. But that wouldn't change if I could suppress them, on the contrary.
We clearly still have a very long road ahead of us (if we survive as a species without destroying the planet first) to true enlightenment and peace.
