And before we knew to look for HIV in blood donations, a number of people got AIDS from transfusions.
So what NEW virus may be rapidly spreading through the homosexual community via promiscuous anal sex, which we don't know about? It's a GOOD idea to exclude blood from members of a community which is a known disease vector.
Homosexuals want to be able to donate blood. They believe HIV was created by the government to get rid of them. So if they can give HIV to everyone else, then the government will release the cure.
