“no you see everyone else did eugenics wrong, im just going to kill the people I think are bad”

weirdly ive noticed alot of behavior like this even on lemmy and even in leftist communities on here. people just get really mad when a post even mentions someone being vegan. similarly i see people demonizing people who for riding bikes and i just get so confused at why they are on lemmy (a very leftist platform) if they despise commonly leftist things
