I think the issue there is how the internet has taken mob justice to the next level, not political correctness; it's a phenomena of both sides of the political spectrum.

It's kind of a scary problem, because we've all done something that offends someone, and what makes the difference between something offensive you've done that nobody cares about and something offensive you've done that makes you the five-minute hate for half the world looks a lot like random chance to me. This sort of thing could happen, really, to any of us at any time.
