Also, very classy of you to paint me as "anti-fluoride" like I would have to have some sort of agenda to question why things are being added to drinking water.
Please abstain, all of you, from acerbic swipes at one another. Both sides are to blame here.
If you must dispute water fluoridation on Hacker News, do so by making careful, factual, respectful comments.
The site guidelines specifically ask you not to call names. That includes both calling each other names as well as calling each others' arguments names (e.g. "woo").
Therefore, "anti-fluoride" seems fitting.
