AIDS didn't just "mysteriously" appear on the scene.
It has been traced back to the primate population. There are several different theories on how it may have been transmitted to humans.
However, scientists all over the world from many different countries have studied the virus now and generally accept the same conclusions.
To suggest that the entire world community of governments and scientists have participated in some giant cover-up against black people is ludicrous.
MOD EDIT: **personal attack deleted.** Especially considering that MOST of the world is not white. White people are actually a minority.
