To claim that dose is the only factor involved is bad faith, or at least overly simplistic. For example, radiation and lead are cumulative. There is no minimum safe dose. Can you say definitively that there is no damage or cumulative effect from regular small dosages of fluoride?

Did you look at the study? The naturally occurring levels are below levels added to water in the US in many of the regions studied.

In any case you should be able to see that I'm not coming at this from some conspiracy nutjob angle but from sourced studies and reasonable thought processes.

My point is not that you are wrong. It's that, even if you are right, it's not some obvious open and shut case.
