Controlling us with fluoride

One of my local cities is talking of taxing or outright banning bottled water.

H tells me last night, "They're banning bottled water in (city name). You know, the Nazi's gave their prisoners fluoride so they could control them. That's why they're banning bottled water you know, they want us to drink tap water so that they can control us."

I say, "OK, so they want us to stop drinking bottled water so that they can control us with the fluoride in tap water?"

H laughs, "That sort of sounds like one of those conspiracy theories, doesn't it? But it's true, tho'."
