This comes as a shock to me, that marriage, or specifically gay marriage, may be an effective method of stopping HIV. I didn't know the foundation was touting gay marriage this way, till I read their release on queer nuptials:
The San Francisco AIDS Foundation applauds the recent California Supreme Court decision to overturn the state’s ban on same-sex marriage, an important step towards equality for all Californians. The Foundation strongly supports marriage equality both because it is an important civil rights issue, and because there is emerging evidence that suggests gay marriage may be an effective HIV prevention strategy.
To their discredit, the foundation's brain-trust didn't see fit to link to any actual scientific proof to back up their startling claim, but it is certainly in keeping with AIDS Inc in San Francisco making pretty unbelievable predictions related to HIV, and offering little to nil proof.
I do give the foundation executives a tip o' the hat for how craftily they worded their statement with qualifiers. Data is "emerging" and it "suggests" there "may be" a link between averting new infections among gay men, and a piece of paper.
Hey all you brainiacs at the foundation, do me a huge favor, please. Link to the emerging evidence and defend your statement with hard proof. There are plenty of specious arguments being made by the rightwing about gay marriage, we don't need AIDS service organizations making bogus claims.
And if SF AIDS Foundation leaders endorse gay marriage as HIV prevention, will they next champion abstinence until marriage?
