I don't know... calling your points above "anti-vax" is like calling having issues with the US gov spending taxpayer dollars on SpaceX to be "flat earther".

Like yeah a flat earther could conceivably be angry about their tax dollars going to Elon Musk's rockets and yeah an anti-vaxxer could conceivably hold all those viewpoints you brought up, but they hold them for wildly different reasons than anyone here would, and anti-vax refers to a pretty specific movement with pretty specific viewpoints behind them.
