I've been meaning to write something about this @aaronsibarium essay but I'll just link to it today as one of the most nuanced explications of certain worst-case scenarios: https://www.americanpurpose.com/articles/weimarization-american-republic/

The key thing is that people really need to see the iterative, both-sides element in a political doom spiral without lapsing into a whataboutism that just constantly excuses their own side. (Good luck.)

To add: I'm not endorsing the essay's argument; I'm citing it to suggest that everyone involved in these debates need to be aware of scenarios where they themselves, through reasonable-seeming moves in an escalating period of political combat, end up contributing to a disaster.
