The first time I saw the irrationality of large groups of adults happened when I was an adolescent in Lafayette, Louisiana. My mom took me to a parish council meeting (in case you don’t know, parishes are counties but they’re called “parishes” in Louisiana because Catholicism) for a debate over allowing fluoridation of the water in the community. I had asked to go because I’ve always been perverse that way. To my family, it seemed like the easiest call: Of course. We had moved from a town in Florida where the water was fluoridated and we were all fine.
