The article does not in fact dispute that people are infected through heterosexual sex. It does state that one is more likely to acquire it through anal sex. Or needles. It suggests that the reason that AIDS infects both sexes to such an extent in Africa could be due to lesions or other infections the inhabitants have acquired there, perhaps due to the tropical climate, real poverty and primitive conditions. It also calls for more of the hard science you have cited.
For all I know your argument is the correct one, but your general rudeness and air of superiority tends to discredit your case.
I'll tone down the "arrogance." It just upsets me because I know women who have been infected through heterosexual intercourse.

The opposite could be true as well. What would a rural witch doctor say caused the purple legions? Demon possession? If purple legions were caused by tropical climate, poverty and primitive conditions, then why don't we have something like this documented as cause of death in past centuries? Also, how many people that were HIV negative were cured of their purple legions by western medicine? If there was a 'purple legion' disease, the west would know, and missionaries would know, and something would be done to cure it. There would be something in the historical record when westerners started visiting and settling in Africa.
