Yes everytime it's "anti" something, but it doesn't occur to you think about the "pro" group. Well actually they are suggesting we remove it or certainly re-evaluate.
The study in question is by the National Research Council:

Sometimes any is bad.
The NRC study have been discussed here before in the fluoridation threads. In summary the study found nothing wrong with water fluoridation because the study didn't look at water fluoridation at all. What the study did look at is drinking water with natural fluoride concentrations much higher than the concentrations in fluoridated water. And yet anti-fluoride groups keep bringing the NRC study because actual research into water fluoridation found it to be safe and effective.
