> The link between fluoride ingestion by children and pregnant women to lower IQ in children has been known for years
Not at the levels it is found in water in the USA. Those studies were done in countries with much higher levels of fluoride.
A low dose of this neurotoxin can still have smaller adverse effects on IQ, and in all likelihood do, especially for fetuses and small children. Lots of countries have banned fluoridation of the water supply. The US has one of the highest fluoride levels in the water supply. The default should be to not add neurotoxins into the water supply (I cannot believe I have to actually say this).
If that were true, nearly the entire state of California would have developmental issues.
Anyway, lots of things in this world that are bad for people in high doses are beneficial in smaller doses. Water is a great example, as are salt and sugar.
This logic is so flawed. We. know the biological mechanisms in the body that makes use of salt and sugar. And we know both are safe in relatively large amounts too.
With fluoride, relatively small amounts in the drinking water is known to cause lower IQ.
But somehow even smaller amounts are safer?
Do you just not see the problem here or are you purposely blinding yourself to the reality because of your political biases? Is it an unconscious thing for you?
You are simply not being rational. You are making excuses and excuses for holding a belief you have had and probably defended for years. And now you are too invested to left the belief go. Just let it go already.

The relationship appears to be linear down to zero, but it’s very hard to study near those levels. From what I’ve seen, the best current science is that the fluoridation levels in typical western countries are reducing average IQ by about 0.5-1.5 points.
For reference, adding lead to fuel was far, far worse.
Any citations?
I suspect it is hard to control for confounding correlations - specifically I would guess it is more likely that poorer areas are flouridated. HV electric power lines and nuclear stations have the issue that poorer people are more likely to live next to those, and poorer people have have worse health outcomes so it falsely appears that both of those cause the health problems.
Or where the people drink much more water
