Found it-- Here is the part related to my post--the rest is crap about prop 8:
According to a recent study by H. Fisher Raymond and Willi McFarland, from the San Francisco Department of Public Health, the social barriers black men face may be responsible for the raging AIDS epidemic in their community. Other races find black men undesirable, limiting their diversity of sexual partners.
The perception is that black men are most likely to transmit HIV. African Americans make up only 13 percent of the U.S. population, yet they account for 57 percent of new AIDS infections. According to the study:
Black gay men are the least preferred of sexual partners by other races, according to the interview data. Black men also are perceived to be riskier to have sex with, which can lead to men of other races avoiding black men as sexual partners. They are also perceived as less welcome in the common social venues of gay men in San Francisco. As a result, black men are three times more likely to have sexual partners that are also black, than would be expected by chance alone.
In the study authors’ view, the combination of attitudes on the part of nonblack gay men, friendships and social networks that are less likely to include blacks, and the environments found in gay venues serve to separate black gay men from other groups. Consequently, the sexual networks of blacks are pushed to be more highly interconnected than other groups, with the potential for a more rapid spread of HIV and a higher sustained prevalence of infection among black gay men.
So the study is saying not only do other races not even want to have sex with gay because they think most of them have HIV but they don't even include them in social events as friends.
