I read Hardy's page there. He has some assertions which are referenced, that make a cogent argument for diminishing the fluoride added to water.
It is an incalculable and illogical leap to consider Fluoride the instrument of the Devil, though.
I think that the
Fluoridation argument is very important, but as a historical event - a pre-internet cobbling together of SOME science, SOME fear, and broad alarmist assertions with untenable claims, that is the intellectual grandfather of the
GLOBAL WAR ON TERRORISM.
Willie Horton was only
Fluoride, with a puppetmaster's hand driving the agenda.
Flouridation is the intellectual ancestor of
Barack-the-Islamofascist.
Fluoride,
F-, is in regular seawater at 1 mg/L, or about 50 micromolar. It's more prevalent than Iodine. Seawater and seafoods pick up enough iodine to satisfy the body's requirement of iodine (in fact, to also cause iodine allergic reactions in sensitive people.) BTW - Iodine has killed FAR more people (from allergies) than fluoride has.
The CDC has some toxicology protocols on fluorides
here. Interestingly, the tea plant, which makes our friendly beverage, aggressively recruits F- and puts it in its leaves (which we distill and drink.) That's why there are no Chinese people left on the planet.
One also should not confuse F- which is chemically inert, with HF and organofluorides, which are not natural products, and can be highly toxic. This is apples and oranges. F- reacts with nothing chemically, and usually becomes insoluble in complexes with things such as aluminum in the soil.
Finally, one can show that our friendly
chloride anion, Cl- will occasionally but rarely photoreact, making the poison gas Cl2 used in WWI as a gas warfare agent - or even worse, Cl* which is the chloride atom, even more reactive.
From simple chemistry, one can discover that the oceans of the world produce TONS PER SECOND of chlorine gas. Of course, this is immediately neutralized in a cycle.
But next time someone complains we're trying to kill the oceans,
FUCK THE OCEANS! KILL THEM BEFORE THEY KILL US FIRST! 
The point is, there's a rudiment of truth in the fluoride story, hashed up with tons of bullshit filler. And we ain't even gone onto the aspartame argument.
Isn't it just logical to stop poisoning humans and the environment? It's just that simple...even the most simple minded could grasp it if they were given a choice.
