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.
Good deeds can be done privately. And many do.
Recording yourself doing good deeds so that you can gain likes and comments for doing it, and broadcast that you belong in the "ingroup", that's virtue signalling.
I'm not saying that kind of action isn't exploitative and actually problematic, but nobody uses the term 'virtue signalling' for that. As a term all it's used for is condemning and dismissing any good deed whatsoever.
It's how right wingers project their completely cynical and transactional motivations onto other people, their shit is like 950% virtue signaling:libs-owned:
