What is the matter with your scientists that they allow your government to be so stupid?

Critics cite studies claiming to have identified a number of possible negative associations of fluoridation, including bone cancer in boys, bladder cancer, hypothyroidism, hip fractures and lower IQ in children.

I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.

Even Chemical and Engineering News noted in 1999:

According to Edward Groth III, an associate technical director of Consumers Union who wrote his Ph.D. thesis in biology on the fluoridation controversy in 1973, pro- and antifluoridationists approach the issue from completely different perspectives. “Proponents see it as a simple public health measure, effective and safe, which they need to ‘sell’ to the public, almost like a box of soap.

In other words, the U.S. government apparently hired the leading propagandist to create the myth that fluoride is safe and effective in order to protect its bomb-making program.
