Thats what the fluoridiots say.

Why is some dumb scientist expert trying to tell me, a person who pays for an internet connection, what the truth is?

Another point that conspiracy bros will bring up is that fluoride is a toxic byproduct of aluminum manufacture and dumping it into the water supply is a cheap way for Alcoa to dispose of it benevolently.

It does do this. However so does ageing, low sunlight exposure, low altitude, ethnicity, sex, nutrition, neuro-divergence, cell phone use, EM fields... you get the idea.

We probably have enough A/B data now to make some inferences yeah? Compare countries with fluoridated water to countries without.

This. How can we be completely certain that something isn't damaging over the long term. I'm not anti fluoride, but healthy debate and scepticism is a good thing, especially when we're all forced to consume a substance with the only alternative being dehydration and death. People need to be free to make their own choices.

Yeah, by this argument lead in the water isn't a concern.

I didn’t know this was a thing when I was younger, but not young enough to not be classified as a moron.

Drank about 7-8 litres of water in 3 hours without going to the bathroom as a contest against a work colleague. Suffice to say I started feeling a little off on the way home, even after going to the bathroom. Years later I finally learned you can drown yourself from drinking too much and the symptoms were eerily close to what I experienced that night.
