I was opposed to adding fluoride to the water. If the scientific literature is accurate, it does help with cavities though; but is it necessary to drink it? I doubt it. Many libertarian capitalists say it's put there to pacify the population in the face of tyranny. I've seen their videos and read their articles. I've seen the pooh-poohing too. A real and public scientific study on that passivity point would be helpful. Perhaps there's one out there already. I just haven't seen it. Does anyone know of one (with a link)?
