Being politically correct has no place in Catholicism.
Sometimes it does, when it concerns things which have nothing to do with sin.
It is perfectly Catholic to refrain from calling disabled people "flids", for example.
It's politically correct to oppose eugenics.
It's politically correct to object to what that liberal commentator was saying about Sarah Palin's Down Syndrome son a few weeks ago.
Political
incorrectness is not always acceptable, and there is a place in Catholicism for
some poolitical correctness.
