Silence Equals Death
The recommendation exposes a fact that the Christian right doesn't want you to know, and carefully evades when proselytizing against same-sex marriage: HIV is no longer a "gay" disease in the United States.
The incidence of HIV infection remains highest among men who have sex with men and among drug users, to be sure. But the greatest increase in HIV infection is among straight, sexually active young folks and African-American women of all ages.
And that is what the Christian right wants to keep hidden.
The fact that HIV/AIDS is no longer a "gay" disease should come as no surprise. Globally, HIV/AIDS has always been a predominantly "straight" disease, simply because there are a lot more straights than gays and lesbians.
HIV/AIDS became a "gay" disease in the United States by epidemiological accident -- the disease was carried into the United States, through Canada, by a gay flight attendant who used the baths for sex, and the disease spread quickly into the gay communities in New York, Los Angeles, San Francisco and other metropolitan areas through that vector.
It is, of course, politically inconvenient for the Christian right to characterize HIV/AIDS as a "human" disease, because the Christian right depends on using HIV/AIDS as a means of convincing straight folks that gays and lesbians live a "dangerous lifestyle".
But the Christian right, by characterizing HIV/AIDS as a "gay" disease, has, in fact, helped spread the disease. Few straights believe that they are at risk, because the facts about HIV/AIDS have been obscured for political convenience. The role of African-American churches has been particularly marked in this respect, because churches have, historically, been a critical source of information within the African-American community.
Silence equals death.
