There was a significantly large group of crunchy granola new-age parents who bought into the anti-vax propaganda re: routine children’s vaccinations, who would have knee-jerk called the other side R/Nazi, as in fascist school board control freaks. I don’t know how much overlap there is between that group and the anti Covid vax crowd, though. (And I tend to picture the spittle-spewing screamers as more the Q side.)
