When I was in college, my editor at the student newspaper called me with an assignment: I was to cover a speech by a radical professor who, my editor breathlessly said, was brilliant “and so PC!”
I asked what that meant, and she said, with some amazement at my naivety, that it indicated “politically correct.”
I had never heard this term before. Of course, it wasn’t long before those juxtaposed letters entered the language and, in the process, went from leftist praise to conservative insult.
