Because a professional group of grifters have been catering to the lunatic tinfoil hat crowd and qtards. Places like the Grifter Pundit, Real Raw News, The Daily Expose, Jack Posobeic ect… these people and websites lie without consequence to generate clicks from the dumbs.
Too much tinfoil and people chasing down one QAnon rabbit trail after another. Some discussions have been only slightly more reality-based than discussions about chemtrails and Lizard People.
The vast majority of things being posted on FR about Covid vaccines (thank you President Trump) are tin foil hat garbage.
