As soon as I saw his picture I was like "Ohhhhhhhhh,
that guy."
Yeah, some of what he says seems plausible, but I thought the amyl nitrite theory was rendered bunk in the early-80s. As for his theories about the virus (and retroviruses in general), you could say that about any infectious organism--of course immunocompromised people are at greater risk. The problem is we still know relatively little about retroviruses, especially HIV. SIV1 for instance, is naturally found in chimpanzees but it doesn't harm them. HIV, however, isn't naturally present in humans and how it came about is still a mystery.

This brings us to OPV/HIV--the only CT I truly believe in...and it's criminal that it's considered a conspiracy theory. I won't bore you with that,
leemajors, but suffice to say that it's an incredibly engrossing topic that--if interested--it'll preoccupy you for weeks. That's where HIV was born, imo...not this bushmeat bull where "we think this guy in 1930 got it" or "some dude butchered a chimp and ate it, causing a mutation and creating HIV." To me, Bushmeat Theory is about as plausible as Adam and Eve.
Check it out sometime.
