You're wise to turn your attention to this disturbing matter. To me, it feels obvious that the whole thing stinks of Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.
Given that the only point of the above comment appears to be to remind people that the OP topic is associated with a low status conspiracy theory and is therefore low status, would one of the people who upvoted it care to explain why?
I've recently learned about alleged dangers to drinking fluoridated water. Amongst them is increased rate of cancer and lowering of IQ. Interestingly enough, wiki doesn't mention this at all, but searching for it brings up a decent amount of (what look like) reasonable results. I am really curious about this, and want to learn more about this. I was wondering if anyone on LW has already conducted a research literature investigation on this topic, or if you just have tips/advice on what to pay attention to when I read the literature.
Thanks!
