...Over at the Boston Globe, a lefty editorial mantra turns culture clash into harmonic convergence: "European Muslims and non-Muslims must learn to live together. Each will have to practice the tolerance that [Theo van Gogh] assassin Bouyeri proudly scorned." They must, must they? As sharia law becomes a democratic option, who will enforce such tolerance?

As conservatives, columnist Charles Krauthammer and blogger-cum-radio host Hugh Hewitt still fight the good fight, but, in these multicultural days, that means sorting through "extremism" and finding nothing too terribly Islamic about it. Mr. Hewitt writes that my arguments of last week were wrong, citing "functioning democracies in Turkey and other predominantly Islamic countries" as evidence of Islamo-Western compatibility. He throws in the loyal host ("millions of loyal British and American citizens") for good measure. Problem is, the extent to which Turkey — where, just incidentally, "Mein Kampf" was a top 10 bestseller this spring — has ever functioned as a democracy is directly related to the efforts of a strong man, Ataturk, to constrain Islam's grip on the country's institutions, replacing religion with a doctrine of Turkish racial and civilizational supremacy. And while it tugs on the heartstrings, the loyalty of individual Muslims fails to neutralize or reform the institutions of jihad and dhimmitude that rise from Islamic teachings. That I even raised the issue, Mr. Hewitt writes, "underscores the almost desperate need for Muslim leaders in the West again and again, to denounce, without argument or sidebar mentions of Israel, etc., the use of terrorism as a weapon." Almost desperate is right.

Having determined that "99 percent" of European Muslims are "peace-loving and not engaged in terror," Charles Krauthammer sounds a similar alarm. "They must actively denounce not just ... the terrorist attacks, but their source: the Islamist ideology and its practitioners. Where are the fatwas against Osama bin Laden? Where are the denunciations of the very idea of suicide bombing? Europeans must demand this of all their Muslim leaders."

Why Europeans? Why not the Krauthammer 99 percent, or the Hewitt millions?...
