True, but sometimes unprotected heterosexual sex w/in the confines of marriage w/o one party knowing of the other's HIV status also gives you AIDS and will kill you. Of this, I personally know as it happened to someone very close to me. However, I understand that such scenarios probably represent a very tiny percentage of actual cases.
With respect to Cynthia's article, I reject her premise that it's black "homophobia" which is the cause of black men on the DL and the rise in HIV infections in the black community. Basically, she's saying that blacks who believe that homosexuality is a sin and should be discouraged are the cause. Blacks who believe such are basing their belief on the word of God and their Christian faith. Thus, Cynthia might as well be saying that Christianity is the cause of the rise in HIV infections in the black community. Just as that is absurd, so is her article.
Now that you mention it, I think she believes just that. The parallel is just too powerful to be an accident. The lady apparently hates Christianity, though she'd never admit it. You nailed her.
