Today is World AIDS Day. I've known three people with AIDS. I currently know one person with AIDS because the other two died. This does not, of course, include the hundreds of people I know... some of which who may have AIDS, and I just don't know about it. And that's because AIDS is indiscriminate. AIDS doesn't care if you're gay. AIDS doesn't care what color your skin is. AIDS doesn't care how old you are. AIDS doesn't care what god you pray to. Anybody can gets AIDS, and anybody who thinks they are somehow immune from AIDS is deluded.
That's because you don't have to actually have AIDS in order to be affected by it. It's just too huge a crisis to think of as "somebody else's problem."
Join the fight against AIDS. Educate yourself.
