You're missing the point. Do you think a president with an R next to their name would be any less of a bloodthirsty moron? So now it's not only "they're bombing Palestine" but also all the other human rights violating shit that happens under a Republican president here at home.
Yes Biden should stop absolutely supporting the genocide, but threatening to replace him with literally the same plus LGBTQ+ discrimination, immigration fear mongering, more destruction of reproductive rights, etc. is certainly not a sane reaction.
The important thing to realize here is that "does the US..." is almost a meaningless category to ask about (at least as far as education is concerned), because each of the 50 different states manages its schooling requirements very differently. Potential course offerings and curriculum are often completely the authority of the individual school districts. So it's almost impossible to ask any given sweeping generalization question about the US school system.
