Hmm, good to know, I thought you were focusing on my response to your comment. The deleted comment was directed at Helga and I removed because, I too, thought it was distracting, but not for the reasons you state. Mostly, because she really was just agreeing with you and not trying to debate. My comment response to you also contained a nugget of what was posted and what I will now say.

The point I made is applicable. Vaccination, eating fruits and vegetables are all well known to benefit scientifically, just like fluoridation. We don't need a community by community research study to prove that. It would be nice to have, but the cost and logistics of that are pretty insurmountable if you want to do it right for the community the size of Port Angeles.
