I don’t think they’d disagree with anything you said there. Their problem, I realize, has nothing to do with flouride. It has to do with the duty of government. They clearly realize that flouride is good for teeth. Maybe they don’t quite understand the sheer amount of flouride required for it to be dangerous, but w/e. The problem is, for them, is that they’re not entirely convinced that governments should be trying to protect their citizens. There’s a belief at work here that an individual shouldn’t need assistance with their wellbeing. Or at least not from a large body that doesn’t have any personal relation to the individual. So the paternalism that is assumed to be good for most people because it has a very high likelihood of doing good, a good that vastly outweighs any potential likely con, is assumed to be bad. This is because that’s a liberty and a responsibility that the government has over the public that could be exploited or neglected, and they believe that a vast body like the government suffers so little influence from the public that should something go wrong, the people would be powerless to stop it.
This has literally been a thing for like… 60 years
