I have provided references to decades of research, the resulting data, and the practical application, all of which support fluoridation of public water supplies within a specific concentration range for public health purposes, by multiple independent organizations, associations, and agencies, worldwide.
You have provided your opinion, conjecture, and vague suspicion. Plus one relevant but debunked article.
If it were true that everyone's opinion, to which one is certainly entitled, regarding matters of fact were equally valid, then we would have a draw. But, that isn't true.
This is a subject about which there has been a great deal of scientific scrutiny for many decades, and about which there is a great deal of scientific consensus. And all opinions are not created equal when it comes to their informed validity.
Of course chlorine is important in the water supply, in order to kill pathogens. It provides a clear public health benefit. Likewise, fluoride also provides a clear public health benefit, and is important in its own realm, especially in certain fluoride-deficient areas.
