A great expression. Was it used in the context of commentary on speech or thought control?
I would say both. There's a situation that took place in a Twin Cities public school yesterday, and it appears that "political correctness" along with "diversity" stifled any common sense reaction to it. A listener called in and railed about both. If I recall correctly, he indicated "political correctness" prevents anyone from saying what should be said and then called it "intellectual fascism."
