> Adding fluoride to water is a strange topic people get very worked up about

Yes. It's weird, it seems to be given a special level of paranoia. And it's a longstanding one, the paranoid general in Dr Strangelove was obsessed with fluoridation.

Lots of substances have arguments over safe legal levels, with varying levels of scientific evidence. This seems to have a crusade, and I wonder who started it.
