The idea that “political correctness” has invaded and conquered American life since the 1960s is a staple of conservative complaint. They assume there could only be one meaning of that concept, that everybody knows exactly what it is, and that it’s everywhere you look, ruining American democratic discourse.
What conservatives call “political correctness” is public criticism of homophobic language, misogynist stupidities about rape, and ethnic slurs. As long as the right wing relies on offensive personal characteristics and made-up “science” instead of reasoned arguments, Americans will correct their language. And liberal organizations like the ACLU will continue to defend their First Amendment right to say whatever they want.
