Its just an odd double standard you have, some chemicals are OK to be added, others are not. My thought process is very simple “fluoride is extremely safe, and everyone deserves the opportunity to live without cavities, lets level that playing field, the same as we do by chlorinating our water”
Fluoride is NOT a neurotoxin in the amounts the found in tap water. Everything is toxic in high enough quantities, and if you think we should ban something because in concentrate it is toxic, then we need to ban water too. If you think fluoride is a neurotoxin in the levels mandated by the FDA, please prove that.
