They havent changed

I think anti-vaxers fall into one, probably more, of these groups:  the terminally stupid, people who dislike government and authority, natural living exponents (described by Billy Connolly as "knitting their own yoghurt"), the mentally unwell, scared folk who want to believe the pandemic isn't real, conspiracy theorists, people looking for a fight, the rudderless looking for direction, the lonely wanting to be part of a group, the gullible.

Those parents who put their kids on the front line to hold placards should be ashamed.

i think youve covered all of them except the bitter incels.
