You make a very interesting point. However AIDS actually threatens all human life on the planet over the very long term. (The fewer humans there are, the greater the chance of species extinction.)
There are credible genetic researchers who theorize that humans once before declined in number (they guess ten thousand or fewer survived over the whole earth as the result of an ice age)and that humans today are descended from that small number. AIDS could do the same thing to the human species.
Pure and utter nonsense! As we've seen in our country, the only people with AIDS are those who engage in non-monogamous heterosexual activity, IV drug users, and those who have sex or receive blood products with those in the previous two groups.
Outside of this nation, AIDS spreads due to heterosexual activity completely outside of our societal norms.
We will survive this epidemic of the perverse.
