Dr. Duesberg's ostracization began with the loss of his annual research
funds from the CDC when he attempted to study the toxicology of AIDS. 
Before that, he was a major voice in retrovirus science.

Anything as important as 'AIDS' must include toxicological studies before
embarking into the complexity and expense of attempting to prove a virus
hypothesis like HIV.

Otherwise there will always be the lingering questions:  

1) Is HIV an industrial/political diversion from the liabilities of industry
(pollution, pharmaceutical scams, etc.)  

2) Is HIV a rationalization for worldwide pharmaceutical exploitation?
