Oh, brother. More fevered crap. Does this help public discourse in any way? Talk about madness - get a grip.

That is a bald-faced lie. Its 'inception', if you can call it that, arose when it became unacceptable to call someone a 'n*gger". It's still completely unacceptable; get over it. If you can't express yourself without using epithets of utter hate, go back to school. That said, political correctness has certainly gone too far. But don't throw the baby out with the bathwater.
