You've done the hard work of making sure you don't throw the baby out with the bathwater: discarding sensible things associated with negative ones. Good!
Gotta also make sure you don't accept nonsense because it's hanging out with something sensible.
For example: kindness is a good state in which to be. But I've heard recently that political correctness is just another word for kindness/consideration from a person who was being rather unkind about it.
Well, with all due respect to reality, if it were merely kindness or consideration with no differentiating features, there wouldn't be a need for a separate term for it. You heard it here first, folks: Every new term entails some new differentiae from the genus. And if you don't think so, stop arguing for Gay Marriage and just accept "Civil Unions".
Different word? Different Concept.
Political correctness is an exploitation of an implicit moral gradient... one direction is uphill and the other benefits from gravity because we have, perhaps unknowingly, accepted some premise. It is usually meant to compel or prohibit certain behavior but the overarching goal is to make you doubt your own mind.
Self-doubt? Fuck that noise. We ain't got time for that.
I'm not saying we should go out of our way to be offensive. We're not Trampeteers or Alt-Right Supremacists. But we need to understand Political Correctness as what it is: Guerilla Warfare against the way your mind sees reality.
Well... Your mind is all that you have. And the extent to which you trust your mind is the extent to which you have self-esteem.
Don't smuggle in the bathwater with the baby. And don't let anyone else do that for you either.
