Science or Ethics?

Elections are looming closer, here in Lethbridge. We are all working hard to educate councillors and citizens. Often the conversations we have become bogged down with differing ideas about how fluoride affects our health. However, many other conversations (or heated arguments if you prefer) are spent hammering out whether or not governing bodies have the right to make medical decisions on our behalf. 

What do you think? Should the decision to keep/remove fluoride be based on medical science or ethics?
