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.
I'll give south park this: when they aren't trying to push an opinion trey and Matt can be really fucking funny. They're at their best when they're just being silly. Fun Times With Weapons and the Guinea Pigs 2 parter as well as Casa Bonita are some of the funniest things I've seen even still. They have shitty political views or when they aren't bad views they're presented really bad but when they try to be dumb as hell or kinda reach into how shitty 4th graders are an play with that it can hit really well.
