back in the days of my youth, it seemed that political correctness was a way for us to be aware of being respectful of each other.
then someone (perhaps tptb?) figured out that it could be used to control us.
taken to the extreme, like plenty of other good things/ideas that started out of grass roots movements.
it always makes me sad when ideas that come from small groups get adopted/coopted by the mainstream. while it would seem a good thing for worthy ideas to spread, it's never long before those ideas are twisted to work against us.
