I bet you all don't even know how HIV started.
I will give you a VERY shortened version. It is the TRUTH,but the media likes to ignore it because of political-correctness.
An african man had intercourse with a monkey.That man contracted the virus from the host. The african man then had sex with a gay flight attendant. Flight attendants travel,you get the point. They spent countless effort tracking and tracing it down to this.
