Dangerous kookery

Wha!?????

There's an article in Harpers in which the viewpoint that HIV doesn't cause AIDS is promulgated? On what planet....

Some of the claims the Harpers article apparently approvingly quotes (the article is not online):

AIDS is actually a "chemical syndrome, caused by accumulated toxins from heavy drug use."

"Many cases of AIDS are the consequence of heavy drug use, both recreational (poppers, cocaine, methamphetamines, etc.) and medical (AZT, etc.)"

"HIV is a harmless passenger virus that infects a small percentage of the population and is spread primarily from mother to child, though at a relatively low rate."

"75 percent of AIDS cases in the West can be attributed to drug toxicity. If toxic AIDS therapies were discontinued...thousands of lives could be saved virtually overnight."

"AIDS in Africa is best understood as an umbrella term for a number of old diseases, formerly known by other names, that currently do not command high rates of international aid. The money spent on anti-retroviral drugs would be better spent on sanitation and improving access to safe drinking water."

I was under the impression that Harpers is a respectable, if a bit dry, magazine. What the hell is going on here?
