I will like to say I've been to anti-vaccine mandate rallies. I have found all of them with no exception to be anything matching the description.
Everyone I talked to believed in one or in most cases many conspiracies up and down the list. There was alot of anti joe-biden pro trump activity and a lot of Evangelical Christian crap (main speaker led everyone in Christian prayer).
Lots of Bill Gates and Fauci hate and lots of 5g is a world domination conspiracy.
I don't deny there may be some people only there about the mandate. But I've found that , that sort of person seems to be rare
