My response to people who bitch about PC.
There's a big ol' fallacy. The old "this problem doesn't matter because that problem is worse" nonsense. I can't for the life of me remember its Latin title, though.
In my opinion, this particular example is more like "this problem doesn't matter because it's only a problem if you deliberately go out of your way to be an asshole."
I'm not sure what image you're looking at, but the one in this thread quite clearly states that violating social taboos in other places has worse consequences than doing so here, therefore political correctness doesn't matter. Either I missed something huge, or it says nothing whatsoever about people going out of their way to be assholes.
