James Reeves - I have challenged you before to provide the specific quote from the CDC that proves your claim that because of drinking optimally fluoridated water, "41% of all children have enamel damage (dental fluorosis) from fluoride and up to 10% of these have moderate and severe dental fluorosis."

That quote does not exist -- the CDC does not make those statements.
https://www.cdc.gov/nchs/data/databriefs/db53.pdf

According to this source, “Among persons aged 6-49, 16% had very mild fluorosis, 4.8% had mild fluorosis, 2.0% had moderate fluorosis and less than 1% had severe fluorosis.  

Your 41% is only in 12-15 year olds and includes all levels of fluorosis.  The CDC does not use the word “enamel damage” -- mild fluorosis actually strengthens the enamel, and there is no indication of 10% of those who drink optimally fluoridated water having moderate or severe fluorosis.  Finally, there are other potential causes of fluorosis besides fluoridation including swallowed toothpaste.
