Nothing wrong with not being unnecessarily offensive/insensitive/tone deaf. I've purged words and faulty/hurtful ideas over the years after either learning their true roots/meanings/intent/end game. If I can avoid making someone feel like crap or uncomfortable simply by avoiding certain words I will (within reason... eg: arseholes may not apply).
I've never liked the term PC and it was never used amongst any of the libby lib "SJW"s I've been surrounded by most of my life. I pretty much only ever see it used as a cudgel against pretty solid arguments for general compassion and empathy for your fellow human.
It's also kind of infuriatingly hilarious that the people who walk around whacking others over the head with that term as a pejorative generally flip the hell out over the tiniest little slight (imagined or otherwise) against their own delicate sensibilities.
It's really quite simple.
