I absolutely stand by calling those two con artists. Jeremy Corbell is a pure grifter, though for the most part a harmless huckster of sensationalism. Knapp with George Noory, use their radio show to push a wide variety of reactionary conspiracy theories, including denials of climate change and COVID, and giving a platform to medical quacks, gun nuts, financial con men, apocalyptic fundamentalists, and other anti-society mythology. All to sell commercials and dubious alternative health products. They are clowns putting on a show for the gullible, not serious researchers.

Railing against the conspiracy mindset is a passion of mine: https://medium.com/inserting-philosophy/what-lurks-beneath-conspiracy-theories-57b7e0a0764a
