Consider what is actually happening: some percentage of the world’s Muslims—5 percent? 15? 50? It’s not yet clear—is demanding that all non-Muslims conform to the strictures of Islamic law. And where they do not immediately resort to violence in their protests, they threaten it. Carrying a sign that reads “Behead Those Who Insult the Prophet” may still count as an example of peaceful protest, but it is also an assurance that infidel blood would be shed if the imbecile holding the placard only had more power.
