In stark contrast, when water fluoridation was first started in the U.S. in 1945, it was promised that only 10 percent of people would suffer from mild dental fluorosis at the then-recommended levels.11Clearly, they were wrong.

Gotta love that 10% is an acceptable amount of harm for no benefit.

Now compare this to gun statistics harm versus benefit. Where Self-defense is statistically significant and gun-related homicides are insignificant when suicides and inner city "youth" are factored out.
