Earlier today, I gave an old, favorite definition of a Marxist: “Someone who loves humanity in groups of one million or more.” In an e-mail, Terry Teachout added, “. . . and kills them in groups of ten million or more.”

Oh, yes. Of course, Pol Pot did fewer — but then, he had a smaller population to work with. He was the Wade Boggs of genocidal maniacs, as a friend and I used to say: He hit for average.
