State enforced vaccination is also terrible - who are these people you know who want it Goose? How would they imagine it would work in practice?
Mainly they are people who see themselves as pro-science, wanting to halt the force of the anti-vaxx movement. They often see themselves as intensely rational and are involved with the Skeptic movement, New Atheism, etc. They also seem very casual about wanting to ban anti-vaxx information like films or websites.
It's become surprisingly big since there have been some larger outbreaks, but the ones I talk to say "Yes, but this is true, it's SCIENCE". No sense that even science is not that straightforward, or the implications for rights relating to the body, speech issues, freedom of thought or belief.
There has been a shift IMO toward this kind of thinking, more authoritarianism but accompanied by a sense that there is this possibility of a lot of very objective knowledge and that it is good to make sure everyone accepts it. There was a thread on the No Outsiders program the other day, and you could see the same split, those who had an issue with the whole thing really, and those who objected only to the gender ideology parts and thought other parts of it were fine because what it was teaching the kids was true, even if some families have other perspective - they just need re-education.
