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.
Not so much a slogan, but the labeling of anything that might improve people's lives as extremism, and calling for being reasonable, and sensible when what they're really calling for is the suffering of poor people.
I can't explain it well but hopefully, you know what I mean
Another one that bothers me is "You just have to look after yourself." and "You can't think about all the worlds problems or you'll go crazy" and other slogans made to shut you up and discourage direct action.
I just tell them there is no position more extreme than continuing down the current path
Conveniently, the "centrist" position for most things is to not improve society somewhat, because improving society somewhat is presented as extreme.
