Political correctness is crap.
It means you cannot say what you want to say. For example, the monster's comment above would be ''You vertically challenged horizontally challenged follicly challenged sexually untraditional melamin-enhanced person'', which is not quite as good. I am short, I am not vertically challenged. Only wusses are vertically challenged. I am pretty sure fat people would rather not be horizontally challenged, or white people melanin-impoverished.
