A tale of icky smugness: Many years ago I read that there was a kind of botulism that mainly attacked Catholics, because it throve in the anaerobic environment of the large vats of potato salad that they made for church picnics. I observed that I was doubly protected from that ailment by being an atheist & disliking potato salad. I then noticed that the feeling induced in me by that observation was indistinguishable from one of superior virtue.
