The condemnation of the letter by Eloise Kailin and her claim, “I fight with the facts, not with threats.”, are commendable.  However, in an article published in the Peninsula Daily News October 30th, she claimed, "A study ... shows child brain damage occurs when pregnant mothers drink waters fluoridated at the so-called “optimum levels” (0.7 mg/L)."  Her use of that study actually demonstrates she fights with fabricated fear rather than facts.  The fact is most mothers did not even drink water "fluoridated at ...'optimum levels'."

I challenge Eloise Kailin to cite and explain the one study she believes provides the most convincing proof that drinking optimally fluoridated water causes harm.  fighting facts with false fear, is a standard anti-F tactic.
