The point about Political Correctness is that it is an attempt to define an ideological and then physical control agenda solely on progressive/leftist terms.
It matters less what those terms are than that no-one else other than in-crowd progressives/leftists gets to have a say in defining them.
Often the issue is really trivial, exposing all the more vividly the true aim: Control.
Above all, no challenge can be tolerated. When one arises it must not be dealt with honestly, since to do that implies surrendering Control.
If there is nonetheless a challenge, because the issue is Control there is little to say.
Which sometimes gets a bit awkward (emphasis added):
"I talked to the parents who are coordinating the talent show, and they feel it’s inappropriate and potentially offensive," Llewellyn Principal Steve Powell said.
When asked what was offensive about Dru’s skit, Powell refused to discuss it.
"I won’t say why it’s inappropriate," he said. "I’m not saying anything to The Oregonian. Why? Because I don’t want to."
That’s clear enough.
