Central to Political Correctness is that homophobia, racism, sexism, bigotry and greed are inherently morally wrong. But the assertion that these things are morally wrong is an absolutist position.
The nightmare scenario for a relativist is to succeed in proving that a position is racist, and have his audience respond "OK, so we're racist. We're cool with that. So what's your point?"
According to all that I have written - concerning political correctness - what is ‘correct?’
According to relativism, there would be no correct position concerning ‘political correctness.’
What would be correct would be based upon one’s POV. No one could decide what is or isn’t politically correct.
See how one can use relativism to refute relativism and/or counter it?
