> Except it's not—fluoride in the drinking water concentrations is proven safe and it doesn't affect brains.
What's amazing is these anti-science wackos are rejecting the largest-scale experiment of all time, with the best evidence that anyone is ever going to have on the subject. We have both temporal and spatial boundary conditions with and without community water fluoridation, where a large population has it and another large population doesn't have it. There is no evidence that the without-fluoridation population has higher intelligence! There is a huge body of evidence that the people without fluoridation have more decayed teeth.
