Last week, the actress Brigitte Bardot, an animal rights activist, was fined €15,000, or $23,000, in France for provoking racial hatred by criticizing a Muslim ceremony involving the slaughter of sheep.

By contrast, U.S. courts would not stop the American Nazi Party from marching in Skokie, Illinois, in 1977, though the march was deeply distressing to the many Holocaust survivors there.

Six years later, a state court judge in New York dismissed a libel case brought by several Puerto Rican groups against a business executive who had called food stamps "basically a Puerto Rican program." The First Amendment, Justice Eve Preminger wrote, does not allow even false statements about racial or ethnic groups to be suppressed or punished just because they may increase "the general level of prejudice."

Some prominent legal scholars say the United States should reconsider its position on hate speech.

"It is not clear to me that the Europeans are mistaken," Jeremy Waldron, a legal philosopher, wrote in The New York Review of Books last month, "when they say that a liberal democracy must take affirmative responsibility for protecting the atmosphere of mutual respect against certain forms of vicious attack."

Waldron was reviewing "Freedom for the Thought That We Hate: A Biography of the First Amendment" by Anthony Lewis, the former New York Times columnist. Lewis has been critical of attempts to use the law to limit hate speech.

But even Lewis, a liberal, wrote in his book that he was inclined to relax some of the most stringent First Amendment protections "in an age when words have inspired acts of mass murder and terrorism." In particular, he called for a re-examination of the Supreme Court's insistence that there is only one justification for making incitement a criminal offense: the likelihood of imminent violence.

The imminence requirement sets a high hurdle. Mere advocacy of violence, terrorism or the overthrow of the government is not enough; the words must be meant to, and be likely to, produce violence or lawlessness right away. A fiery speech urging an angry racist mob immediately to assault a black man in its midst probably qualifies as incitement under the First Amendment. A magazine article - or any publication - aimed at stirring up racial hatred surely does not.
