"Canada's Thought Police"

This will put a real damper on free discussion in Canada.

Celebrated author Mark Steyn has been summoned to appear before two Canadian judicial panels on charges linked to his book "America Alone."

The book, a No. 1 bestseller in Canada, argues that Western nations are succumbing to an Islamist imperialist threat. The fact that charges based on it are proceeding apace proves his point.

Steyn, who won the 2006 Eric Breindel Journalism Award (co-sponsored by The Post and its parent, News Corp), writes for dozens of publications on several continents. After the Canadian general-interest magazine Maclean's reprinted a chapter from the book, five Muslim law-school students, acting through the auspices of the Canadian Islamic Congress, demanded that the magazine be punished for spreading "hatred and contempt" for Muslims.

The plaintiffs allege that Maclean's advocated, among other things, the notion that Islamic culture is incompatible with Canada's liberalized, Western civilization. They insist such a notion is untrue and, in effect, want opinions like that banned from publication.

Two separate panels, the British Columbia Human Rights Tribunal and the Canadian Human Rights Commission, have agreed to hear the case. These bodies are empowered to hear and rule on cases of purported "hate speech."
