I think those who do NOT believe in conspiracy theories make up the group of the worse followers. They are unimaginative, dull, and boring. They are mostly very rude to anyone who dares have a thought outside very narrow definitions. I love mandela's, flat earthers, moonischeese-ers, moonisspaceport-ers, moonisprojection-ers, mooniscoldlight-ers, pizzagaters, 911ers, obamaistheantichrist-ers, trumpistheantichrist-ers, and many other delicious flavors of truthers.
The antivax-ers are just better people than the vax-ers. They are patient and kind instead of stuckup and snobby. I think the vaccines cause people to be hateful to other people. Including the people who are constantly ill from flu shots - it makes them very grouchy to be sick all the time.
