Your answer, "because they are all in bed together. Pride has many motives." is obviously only your opinion unless you can provide some specific facts (evidence) to prove why each of those organizations  continues to recognize the benefits of fluoridation.

What evidence do you have that the representatives of these organizations have not done "honest research" and come to the conclusion that fluoridation with silicofluorides is both safe and effective.  

It seems to me that the only evidence you have that "they are all in bed together" and "...pride..." is that the conclusions of the overwhelming majority of scientific and health experts that fluoridation is safe and effective do not support your beliefs and opinions. 

Public health programs are implemented for the overall benefit of the citizens.
