Anne Applebaum says it better than I could in her column in Slate & the Washington Post.

But we can all unite in our support for freedom of speech—surely the pope is allowed to quote medieval texts—and of the press. And we can also unite—loudly—in our condemnation of violent, unprovoked attacks on churches, embassies, and elderly nuns. By "we" I mean here the White House, the Vatican, the German Greens, the French Foreign Ministry, NATO, Greenpeace, Le Monde, and Fox News. Western institutions of the left, the right, and everything in between. True, these principles sound pretty elementary—"we're pro-free speech and anti-gratuitous violence"—but in the days since the pope's sermon, I don't feel that I've heard them defended in anything like a unanimous chorus. A lot more time has been spent analyzing what the pontiff meant to say, or should have said, or ought to have said if he had been given better advice.

All of which is simply beside the point, since nothing the pope has ever said comes even close to matching the vitriol, extremism, and hatred that pours out of the mouths of radical imams and fanatical clerics every day of the week all across Europe and the Muslim world, almost none of which ever provokes any Western response at all. And maybe it's time that it should: When Saudi Arabia publishes textbooks commanding good Wahhabi Muslims to "hate" Christians, Jews, and non-Wahhabi Muslims, for example, why shouldn't the Vatican, the Southern Baptists, Britain's chief rabbi, and the Council on American-Islamic Relations all condemn them—simultaneously. Equally, I see no reason why Swedish social democrats, British conservatives, and Dutch liberals couldn't occasionally forget their admittedly deep differences and agree unanimously that the practices of female circumcision and forced child marriage are totally unacceptable, whether in Somalia or Stockholm. Surely on this issue they all agree.

Maybe it's a pipe dream: The day when the White House and Greenpeace can issue a joint statement is distant indeed. But if stray comments by Western leaders—not to mention Western films, books, cartoons, traditions, ethics, and values—are going to inspire violence on a regular basis, I don't feel that it's asking too much for the West to quit saying sorry and remain united, occasionally, in its own defense. The fanatics attacking the pope already limit the right to free speech among their own followers. I don't see why we should allow them to limit our right to free speech, too.

It shouldn’t be difficult – but too many voices in the West would rather dhimmify than fight.
