Well, I have lived in the North East all of my life and the water here is fluorinated and I can't say I know of anybody having any health issues due to it and I know I am certainly one of the most anti authoritarian people on this board so I really doubt the 'makes people stupid and docile' line. I would like to see a proper scientific study on the subject as there should have been before they introduced it up here, however I won't worry about it so much that I stop drinking tapwater. Seems to me there is a fair bit of scaremongering around the subject.
Hang on while I stick a scary image in my post to make it have more impact :
