Dworkin got this one right.
Professor Ronald Dworkin is not a classical liberal. And there is much to criticize him about. But the following quote from an essay he wrote for the New York Review of Books is not one those things. In this part of his essay he is correct.
Muslims who are outraged by the Danish cartoons note that in several European countries it is a crime publicly to deny, as the president of Iran has denied, that the Holocaust ever took place. They say that Western concern for free speech is therefore only self-serving hypocrisy, and they have a point. But of course the remedy is not to make the compromise of democratic legitimacy even greater than it already is but to work toward a new understanding of the European Convention on Human Rights that would strike down the Holocaust-denial law and similar laws across Europe for what they are: violations of the freedom of speech that that convention demands.
