What do we know about our next door neighbors? Do we know what they do for work? How they feel about the school board? What their hobbies are? Well, if you don't know, why are you criticizing them. "Their lawn is to high." "They let their dog bark all night." And we can find many other things to criticize them for, right? Well, why not ask them?
A simple question can render a simple answer. It's that simple. When you see them out and about, with people you find to be questionable, ask them why, don't feign a smile and be pleasant and later, when you're away from them, criticize them.
Political Correctness is similar, in a way, in that when you say something to someone, you're met with criticism but also a fair amount of resistance in what you are saying. And, with that, the person your are talking to may get 'offended' in some way. To talk in ways to others so they won't get offended is, in essence, 'political correctness'.
It's time we stop walking on egg shells when it comes to political correctness. If others are offended, that's not your problem. They were 'sheltered' in some way, by being indoctrinated with politically correct propaganda.
