Honestly I think the concept of political correctness was hijacked on day 2 by people desperate to play the victim card by any means necessary..
Notice, no one ever lets things go or subtly informs people that other wording may be better ....its always OUTRAGE and people are UPSET, feelings are HURT..and its always in relation to something that doesn't effect them in any way shape or form...
Sounds to me like certain people want to be victims for all the sympathy and attention that being a victim brings, but in their safe, secure little world they never get to be one, so being offended on someone elses behalf is the next best thing...
and we give in (like giving in to a child who throws a tantrum) and it makes things worse.
Thats my two cents on the subject..
