"In the mid-1990s molecular biologists identified at least 8 different subtypes (or “clades” or “strains”) of HIV that were infecting various people around the world. Remarkably, it turns out that the “B” strain is the predominant strain infecting gays in the U.S.
Even more remarkable is that this strain of HIV has an “affinity” to infect rectal tissue, thus explaining why gays are more likely to get AIDS than straights.
In contrast, the HIV strains common in Africa have an affinity for vaginal and cervical cells, as well as for cells of the foreskin of the penis. Thus, HIV is more likely to infect heterosexuals in Africa.
How do we know this? Max Essex (a Harvard veterinarian who performed pre-AIDS experiments transferring feline leukemia virus between cat populations) tested subtype E strains of HIV from Thailand. He discovered that this Asian strain readily infected women’s genital cells of the vagina and cervix. But the “gay” B strain of HIV did not infect them as easily.
AIDS experts tell us American AIDS came from Africa, but the strain of HIV prevalent in gay men is almost never seen in Africa! How is this possible?
Were strains of HIV engineered to adapt easily to cells likely to be infected in gay sex? Or adapted to genital cells involved in vaginal sex?"
It does seem odd that the AIDs is predominantly heterosexual binding in Africa and homosexual binding in the USA.
