"Ridicule is a distinct kind of expression..."

Writes Ronald Dworkin in the New York Review of Books:

... its substance cannot be repackaged in a less offensive rhetorical form without expressing something very different from what was intended. That is why cartoons and other forms of ridicule have for centuries, even when illegal, been among the most important weapons of both noble and wicked political movements.

So in a democracy no one, however powerful or impotent, can have a right not to be insulted or offended. That principle is of particular importance in a nation that strives for racial and ethnic fairness. If weak or unpopular minorities wish to be protected from economic or legal discrimination by law — if they wish laws enacted that prohibit discrimination against them in employment, for instance — then they must be willing to tolerate whatever insults or ridicule people who oppose such legislation wish to offer to their fellow voters, because only a community that permits such insult as part of public debate may legitimately adopt such laws. If we expect bigots to accept the verdict of the majority once the majority has spoken, then we must permit them to express their bigotry in the process whose verdict we ask them to accept.

Yes, of course: free speech is part of the mechanism of democracy, and ridicule is an especially important form of political speech.
