I once found myself stuck in a biker bar west of Dallas. I had to listen to this old timer Hell’s Angel go on and on about fluoride conspiracies. Some of them are pretty wild - “fluoride is created by nuclear weapons construction as waste and the government has to get rid of it somehow, so in the water it goes” for example. The rest of the evening is a little hazy but I remember that.

Incidentally, I used to think Hell’s Angels were just retired dentists.
