By the way, just because a term is politically correct doesn't mean you won't get into trouble. Negroid is the correct scientific term for black people, but I dare you to start using it in public. The word niggardly is a fine term, but most people don't know that. Most midgets I know get more offended by the term "dwarf" which is technically the correct term.
Basically, people consistently want what they are called to change because they associate the negative attention they get on the words that are used. They give certain words power and as such, they want the words to change every now and then so they can stop associating them with negative experiences. If they called midgets little people in the carnivals when they were sideshows, they would all get getting offended by the LP term and they would be asking us to call them midgets.
