The Bloomington Vegans were marching because of hot dogs. Apparently, the idea of pork and beef leftovers being used to produce hot dogs was particularly offensive to them. They would prefer we use tofu dogs at the ballpark. I could argue that nobody has actually proven that hot dogs really are pork or beef, but I figured it was irrelevant. I don?t like to debate the Bloomington Vegans. They are an unhappy clan ?always quick to get into a debate about culinary morality. I don?t look down on them. I just feel sorry for them. I hope there are happy vegans somewhere.
