Political correctness mainly exists so people who fight against political correctness can have a smug sense of righteous indignation. 99% of the time, the accusation of political correctness is blown horribly out of proportion with a few well placed lies mixed in. Which is why people thrive so much on the rare stories of people ACTUALLY being silly and oversensitive, like (from appearances only) this instance. Overall, there are far less constraints on behavior from any form of political correctness then there are from those people who will stare angry daggers at you for daring to impune on them by trying to give half a damn about your fellow mans feelings.
