You are right, but he is correct, even if he didn't provide the best sources.

whatever. enjoy your chemical-addled water supply you bunch of cattle.

MA, about 95% of fluoride added to the public water supply is produced from phosphorite rock.

I've found LiveScience is a reliable source.

Fluoride is added to public water supplies at an average concentration of about 1 part per million (1 ppm) or 1 milligram per liter, or slightly below. Naturally occurring fluoride concentrations in surface waters depend on location but are generally low and usually do not exceed 0.3 ppm. Groundwater can contain much higher levels, however.
In 2015, the U.S. Department of Health and Human Services issued a recommendation for the optimal fluoride level that should be in drinking water to prevent tooth decay. This new recommendation is for a single level of 0.7 milligrams of fluoride per liter of water, opposed to the 0.7 to 1.2 milligrams per liter recommendation issued in 1962, which is now the standard.

The whole point of water fluoridation is to help prevent tooth decay. Any substance is toxic at a certain level of concentration, and the levels in water are nowhere near that level. You are not test subjects - scientists know the full effects of NaF and have deemed it perfectly safe for drinking.

Is fluoride bad for you?
It depends who you ask; fluoride is unquestionably toxic at certain concentrations. The most comprehensive report on fluoride was published in 2006 by the National Research Council, done at the behest of the Environmental Protection Agency. That group found that the upper limit for fluoride, at 4 ppm, was too high to prevent a certain percentage of kids from developing severe dental fluorosis and recommended the EPA lower this limit..

So they lowered the limit. It's the same thing when people go on about how GMOs are bad for you, it's bollocks. How any of us have been drinking water containing NaF our entire lives?

Every point in that article is easily disproven.

1. There hasn't been any global warming since 1997? Yes there has.
2. There is no scientific consensus that global warming is occurring and caused by man? Yes, there is.
3. Arctic ice is up 50% since 2012? No it isn’t.
4. Climate models showing global warming have been wrong over and over? No, they haven’t.
5. Predictions about the impact of global warming have already been proven wrong? No, they haven’t.

I'm disappointed you took the bait, Manco.
