If petitions don't work...
...then petition with your wallets. Their customers have spoken and they don't care because they know they don't have to. If enough people refuse to pay their water bills until fluoridation stops then I'm sure they'll start listening.
If a person wishes to have a dental cavity, yes, it is an absolute human right that they be permitted to have one if they so choose.
That sounds like child abuse to me.
This really is a no-brainer; fluoridation is perfectly safe (as evidenced by its widespread use elsewhere, Birmningham being a very good example) and is sorely needed in our area. Let's allow the health professionals to do their jobs, and not let a bunch of Daily Mail reading busybodies impede the future health of our children.
