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.
"authoritarianism"
There's nothing that's not political so I'm going whole hog into it
And its twin siblings, "Totalitarianism" and "Police State".
:sicko-pig:
This was gonna be my suggestion too, it's one of the most thought-terminating words of the last few years. Whatever definition it once had has now been entirely boiled down to "When a foreign government does something that is against Western interests". You could be the most tyrannical regime in existence, you could bolt cameras and trackers onto every person, you could enforce arbitrary clothing standards, you could limit the mobility of every person in the country to be a tiny area for maximum control, but you would still not once be called authoritarian so long as western capitalists had unfettered access to your economy.
