Yeah, beyond that I was mostly responding to the assertion that “Americans are stupid and easily manipulated.”

No, they are responding to an imperfect system that punishes them for having strong morals. Far from stupid, it’s actually quite rational. The best thing you can do if you care about not having to choose between genocide and even more genocide is get involved in pushing ranked choice voting through ballot measures, lobbying your state legislature, or hell, start with just municipal elections if you think you can get that done.
