With the gay community it has overwhelmingly been about legitimization of their lifestyle. Anything that cast a negative doubt on their lifestyle MUST be eliminated from the public square so as to facilitate the "Image" of normalcy for their lifestyle in the eyes of the public at large which does not look at it the same way they do.
Concurring BTTT.
And when homosexuality got thrown into the PC and "diversity" platform they got a big boost. Lets face it, we cannot be a true multicultural society unless we become an "anything goes" society. Now if thats what we want, then of course we should mix a little homosexual blood into the blood pool. In fact, a true multiculturalist would want the blood mixed with all donated blood before it could be given to anyone. I hope this is one of the last gasps of the PC movement. It has to be killed now.
