When I'm with leftists, I don't call the term "political correctness." I use the term "cultural marxism."
They invariably proffer me a confused look. I then happily explain it for them: "Cultural marxism? You don't know what that is? You know, it's now called political correctness."
It usually shuts them up, and perhaps gets them thinking.
Perhaps.
I like it, but they are probably thinking you’re the Marxist or at the very least, an a88hole just for MAKING them think.
