This is like refusing to use the word "history" because it has "his" in it. Nevermind that in order to do so one must ignore the etymology of the word which shows it has absolutely NOTHING to do with masculinity or femininity.
I think that's what PC is. It's dumb people thinking they're smart because they see all this "injustice" in our language....only if they were actually intelligent they would know that the "injustice" they see, most of the time, has absolutely no relation to what they think it does.
So, perhaps PC-ness can be blamed on our poor educational system.
