how does the term “politically correct” even make any sense?

what is political about not erasing and insulting a group of people or someone’s identify? (tw for various slurs)

“What do you mean you prefer to be called lesbian/queer/gay instead of dyke/fag? YOU’RE SO POLITICALLY CORRECT!!!!!!!!!!!!!!”

“What do you mean by ‘people with disabilities’? Why can’t I say ‘invalids’? YOU’RE SO POLITICALLY CORRECT!!!!!!!!”

“What do you mean I have to say Asian/Asian-American instead of “chink”? GOSH PEOPLE ARE SO POLITICALLY CORRECT THESE DAYS!!!!!!!”

“What do you mean I should say “Happy Holidays” instead of “Merry Christmas”? YOU’RE TAKING AWAY MY CIVIL RIGHTS!!!!!!!!!!!!!!!!!”

I guess when you’re a privileged person who has never had to consider how the things you say oppress other people, and you don’t have any real interactions with said people, changing your ways is just a matter of politics rather than being a decent human being.
