AIDS was originally called GRID...which stood for Gay Related Immune Dysfuction. The idea was that it was caused by rec drugs such as cocaine, heroin, poppers, etc.....
Keep in mind that these people were doing some rough things to their bodies. poppers are a cause of Kaposi's Sarcoma...a rare skin cancer that many gay men were exhibiting.
Also consider that it was *gay bottoms* that were coming down with the disease. Semen is immuno suppressive and enters the blood via the rectal lining, which is hemorraged easily in passive anal sex. And consider that these people were having lots of sexual contacts ans sex parties-treatment of the STD's was by Antibiotics
, which again are immuno suppresive when used/abused chronically.
Add all of this up, and is it any real suprise that so many gay men developed *AIDS*?
