Weinstein repeated discredited theories to Rogan about HIV not being the cause of AIDS, alarming and infuriating public health experts.  

Bret Weinstein, the evolutionary biology professor turned podcaster and ivermectin guy, repeated a series of discredited pseudo-theories about AIDS in a recent appearance on Joe Rogan’s podcast. Weinstein, a frequent guest, told Rogan that he found the theory that party drugs like poppers cause AIDS to be “surprisingly compelling.” (It is not.) Weinstein also told Rogan he came to these ideas by reading a recent book by anti-vaccine activist and presidential candidate Robert F. Kennedy, creating a sort of unholy turducken of misinformation passed onto an audience of millions.
