HIV is a deadly virus. It causes AIDS. If you contract HIV, unless you are prescribed antiretroviral drugs, you will likely progress to AIDS within a decade and die shortly thereafter. This is not, however, how certain guests on Joe Rogan’s show see it. The other day on the nation’s No. 1 podcast on Spotify, Rogan had on a frequent guest, Bret Weinstein, a former professor of evolutionary biology. Weinstein spoke about arriving at the view that HIV doesn’t play a causal role in AIDS.
