Since the cross-over of SIV to humans, one thing is certain. Stopping homosexuality will not stop the spread of HIV in humans. It's clear that although the 'first' reports of AIDS in North America were amongst gay men, the organism existed long before that in the human population, and not only amongst the homosexual population.

"Four of the earliest known instances of HIV infection are as follows:

A plasma sample taken in 1959 from an adult male living in what is now the Democratic Republic of the Congo.9
A lymph node sample taken in 1960 from an adult female, also from the Democratic Republic of the Congo. (10)
HIV found in tissue samples from an American teenager who died in St. Louis in 1969. (11)
HIV found in tissue samples from a Norwegian sailor who died around 1976. (12)
A 1998 analysis of the plasma sample from 1959 suggested that HIV-1 was introduced into humans around the 1940s or the early 1950s. (13)

In January 2000, the results of a new study (14) suggested that the first case of HIV-1 infection occurred around 1931 in West Africa. This estimate (which had a 15 year margin of error) was based on a complex computer model of HIV's evolution.

However, a study in 2008 (15) dated the origin of HIV to between 1884 and 1924, much earlier than previous estimates. The researchers compared the viral sequence from 1959 (the oldest known HIV-1 specimen) to the newly discovered sequence from 1960. They found a significant genetic difference between them, demonstrating diversification of HIV-1 occurred long before the AIDS pandemic was recognised."

So, unless the name of the game here is to slam homosexuals, then please deal with the facts.
