Oh my god. I'm agreeing with Ustwo
Yes, she is a dumbass. The idea that HIV is a bioweapon is dumbass.
If you're gonna make a bioweapon, you make one that can survive outside the body for more than a few seconds. You make one that's spread by respiration, not sex - it's easy to avoid sex, it's not so easy to avoid breathing. You make one that spreads very fast and to multiple people from the primary source. i.e. AIDS can only be transmitted to one person at a time (unless you get really kinky). An effective bioweapon virus would be spreadable to an entire room of people at the same time from one person - i.e. an airborne virus.
Finally, what possible motivation could anyone have for attacking poor people in Africa. They don't exactly hold a grip on anything in the world. If HIV were a bioweapon, it would have been released in the United States or the USSR - somewhere with a lot of influence that has targets people would actually give a crap about killing.
