1.  Estrogen does not already exist in the water naturally as does fluoride.  

2.  Estrogen has documented side effects.  Optimal level fluoride does not.

3.  There is no documented evidence that adding estrogen to the water supply would diminish prostrate cancer and domestic violence.  There are volumes of peer-reviewed scientific evidence demonstrating  that adjusting the fluoride concentration in water significantly reduces dental infection.
