I did some calculations with thier numbers:
You're over 6 times more likely to have HIV/AIDS if you're black than if you're not.
You're 10 times more likely to have HIV/AIDS if you're gay than if you're not.
A gay black person is 30 times more likely to have HIV/AIDS than a straight, non-black person.
Of those 1 million cases of HIV/AIDS:
210,000 are gay blacks, which is 7.5% of the gay black population.
240,000 are gay non-blacks, which 1.3% of the gay non-black population.
260,000 are straight blacks, which is 0.8% of the straight black population.
290,000 are straight non-blacks, which is 0.1% of the straight non-black population.
1.3% of blacks are HIV/AIDS positive, as opposed to 0.2% of non-blacks.
2.1% of gay people are HIV/AIDS positive, as opposed to 0.2% of stright people.
These numbers use 2000 US census data for population and ethinc information. The gay population was estimated to be 7.5% of the total population, and evenly spread among ethnic groups.
Everything is rounded to within about 0.1%.
