The one I'll bring up, as an example of "not as political" but still harmful, is used by chuds, libs, and leftists alike as a throwaway putdown, insult, and thought terminating cliche.
"WHO HURT YOU?" :very-intelligent:
The damage it does to social discourse comes from further normalizing the implication that being hurt is a mockable thing that deserves ridicule and dismissal, and the other problem is that it makes sincere suggestions to actually seek actual help, stated in good faith, get lost in the haze of :reddit-logo: tier le epic takedowns.
My runner-up is "grindset." The entire concept is poison and seems to contaminate impressionable brains at an alarming rate. Motivating people to improve themselves and achieve things in a healthy way is harder to do when so much online discourse is chuddy grifters jerking themselves off while bullying people for not "grinding" hard enough, no matter that person's situation.
Also "makes fun of everything" means that Mormons get made fun of for being silly and goofy and having dumb lore(Also goes for how they mock Scientology), while trans people get made fun of through
CW: Describing transphobic south park shit
Comparing them to surgically trying to be black, or a dolphin. Or the whole separate episode from that shit where trans women are mocked as literal macho men trying to brutalise cis women.
They'll superficially make fun of everything except their own empty superficial rich white nihilistic libertarian asshole ideology.
