That was the comment of one comic poet on the Ostracism of Hyperbolos at Athens in around 417 BCE. He was considered "beneath" the punishment. The same applies to David Irving, currently being held in Austria on charges of Holocaust denial. Irving is a jerk, a fraud, and an anti-semite, but he shouldn't be in jail for it. Quite apart from the strong freedom of speech arguments (which I covered here, when he was planning a trip to New Zealand), the threat of imprisonment dignifies him. It gives his views far more credence than they deserve. Potsherds weren't invented for the likes of Hyperbolos, and prisons weren't invented for the likes of Irving. He should be allowed to make a fool of himself in public (and incidently provide a platform for people to prove it) as much as he wants.
