A 5-year period of gay celibacy? That's an insult.
And what about blood from gays who don't admit to being gay? How safe is that blood? Or gays and straights who are HIV+ and don't know it, and get to donate anyway?
What happens to that blood? Doesn't it get tested after the draw, to screen-out HIV? If not, that means HIV+ blood is in the blood bank system right now.
And if it's not, because of post-draw screening tests, then why are gays banned at all?
This is a very emotional subject for me, because I was permanently banned from giving blood in the US, right after 9/11, when I attempted to donate and admitted I was gay during the screening. Yet my blood remains totally disease-free to this day, never an STI in my life, and a rare type, as well.
But I can't donate. Yet any homeless person or prostitute can walk into a US blood bank off the street and add their blood to the supply. Wonderful system.
