I agree with Citabria.
The problem with you liberals is that you too often wanna effectivly ban or restrict something because YOU may feel its offensive and it may make you feel guilty. "Japs" is a perfect example I think, even though I dont really like or use that term personally.
Would you wanna ban Brit, Yank, Kraut, Ami, or Frog?
All these have a certain history too, dont they?
