Hence why tampering with water in any way is absolutely beyond stupid.
I choose not to poison myself.
Given that things like chlorine and chloramines are put into drinking water to disinfect it, the thought of "tampering" with water to avoid things like e. coli is fine by me. I'm honestly not quite sure why scientists are just figuring out that fluoridation is bad - it's been around, at least in the U.S, for over 60 years - easily enough time for people to notice any problems.
