As scornful as I am of fast food, I still think Los Angeles is one taco over the line in proposing a ban on it. A Big Mac is no different from foie gras: Someone wants to eat it, this is a free country. And once they come for the chicken nuggets, where would it end? Cupcakes can make you fat, too, with or without trans fats. Not to mention the fact that driving is not exactly good for anyone’s health. I see Sinclair Lewis quoted everywhere lately, saying fascism will come to America wrapped in a flag and carrying a cross. But he might be wrong about the outfit. I predict a nutrition lab coat.
