The article may be stupid, but it isn't as stupid as your comment.
The natural, obvious, and unmentioned reason that so many African women are HIV positive (if that is indeed the case) is they HIV is a harmless passenger virus, riding inhumans for millenia, probably transmitted during gesation, and having Africa as its natural home.
So what? The article is called The Big Lie...that my friend, is hogwash, pure and simple. Hiv is spread a number of ways. One of them is unsafe vaginal sex. If legal, I could provide you with the names and phone numbers of people infected by vaginal intercourse. I wish you could meet them and explain to them that they didn't really have HIV.
