Anti-vax has never really been a thing though. I don't know what the data is these days, but it used to be like 1% of the population who were anti-vax.

We have the same thing going on with racism in the West where people are convinced racism is a much bigger problem than it actually is.

And whether it's anti-vax or racist beliefs, when you start attacking people for holding these views you always end up inadvertently encouraging people to start asking why that is and they end up down rabbit holes.

No one believes peas cause cancer for example, but I guarantee one of best ways to make people start to believing peas cause cancer is for the media to start talking about how some people believe that peas do cause cancer, then for sites like YouTube and Facebook to starting ban people who talk about it. Because if they allow people to talk about UFOs and flat Earth conspiracies why are they banning people for suggesting that peas cause cancer? Is there some kind of conspiracy going on funded by big agriculture? You can see how this type of thinking happens.
