yeah. extremism seems to be the norm here. and you will be harassed and insulted and told your a POS if you even mildly disagree with the extremist narrative. most of the content seems to be angry leftism idealism that reads 'young idealist' who thinks ideological purity is the solution to problems and is incapable of acknowledging a complex and pragmatic approach to any issue at all. and generally people who are totally detached from the average person's perspective/experience, as per your windows comment.
it's just people being people. people don't like anyone who disagrees with them. it hurts their feelings. so they act out.
i will say at least the mods don't ban you for disagreement or injecting a dose of reality into a simplistic ideological narrative about the world... which is why i gave up on reddit.
