> Third, "politically correct" is a label principally used by reactionary dullards to dismiss arguments or objections that they see as excessively leftist.

Mind you, some people are communists, some people are knee-jerk excessive leftists, etc... but if that's true in a particular situation, you can just explain why it's true. Calling it "political correctness" is just a lowbrow dismissal.
