Roosh v has joined the debate, now among Covid critics, about whether viruses exist at all, or whether if they do in some sense exist, do not play the causal role that mainstream medicine says. The main arguments are basically epistemological, based upon questions of proof and evidence. It is interesting, but one claim is that there has been no isolation of SARS-Cov-2. That is heavily disputed on the internet by the fact checkers. I don’t know. Something is definitely going on, and the postulation of a virus as the causal mechanism explains more than numerous ad hoc hypotheses about environmental causes. Still, interesting to think about, at a level that the mainstream seldom does.
