For the last few years when anti vaxxers have voiced any concern they have been ridiculed by mainstream media and social media. And probably many of the first anti vaxxers where hired to be ridiculous and act out like someone that cannot be taken serious. Anyone who questioned anything (vaccines and other things) where quickly bunched together with crazy nut job conspiracy theorists like the flat earthers. Maybe the flat earthers is part of this to really make sure anyone wo questions the nerrative is made to look dumb and ridiculed. Now whenever i hear people around me talk about the jab, they parrot the same lines over and over like a good NPC, that who ever doesn't take the jab is dumb, naive, stupid...
Naturally i don't have sources for this, as i just thought of it. My own little conspiracy theory.
