Speaking of crackpots, PLOS has a good article exposing some of the HIV deniers, including our favorite character Duesberg:
"Interestingly, alternative hypotheses for AIDS causation depend on where the patient lives. In Africa, HIV deniers attribute AIDS to a combination of malnutrition and poor sanitation, i.e., they believe that AIDS is simply a relabeling of old diseases. In America and other wealthy countries, they claim AIDS is caused by drug use and promiscuity. Duesberg has long been an advocate of the idea that the use of “poppers,” or amyl nitrate, is a cause of AIDS in the gay community . With the identification of AIDS in individuals who have never used poppers, this hypothesis has been widened by HIV deniers to implicate a number of recreational drugs (cocaine, crack, heroin, methamphetamines) as well as prescription drugs such as antibiotics and steroids in the etiology of AIDS. HIV deniers have criticized the idea that immunosuppression due to infection with HIV could result in all of the different infections that characterize AIDS, and yet they support the idea that poppers or other drugs—including many that have not been shown to cause severe immune deficiencies—could cause AIDS. In the past decade, the very drugs used to treat HIV/AIDS have come under fire by HIV deniers, who have suggested that the medicines themselves are a cause of AIDS"
You know I've never figured out why pharyngula is so popular, it's always the same creationist bashing, with a picture of a cephalopod thrown in from time to time. I mean I dislike creationists as much as the next scientist, but man it gets old quickly, the bayblab is soo much better.
