Well, my original post on the Paris riots below certainly sparked some controversy in the comments section.
The discussion went in the direction of the problem of passages in the Koran that advocate the killing of infidels. That was not really where the original post was pointing, however. My joke about "insurgents" was more of a jab at the ridiculous coverage of events in Iraq and the endless pontificating on America's failings from the "enlightened" French government.
France has the largest Muslim population in Europe now. These riots are, no doubt, the result of the growth of that population in a country that has a long historical obsession with the concept of French identity and the uniqueness (and superiority) of French culture. Until now, my impression is that the French have tried to pretend that there would be no problem assimilating a large Muslim presence into its modern, secular state.
Unfortunately, many of the cultural norms and beliefs that the immigrant community bring to France cannot be squared with a modern, secular state. You can't have one community that believes in French jurisprudence, for example, and another that wants to live under sharia law. This tension was revealed recently in the controversy over banning headscarves from French schools.
It is, therefore, not surprising that the Muslim community is mostly ghetto-ized. This doesn't excuse the rioting, but it does provide some context.
I am not assigning value judgments here. I am merely pointing out that France has a mess on its hands and not a lot of ways to square the circle. I suspect this is going to get uglier because the problem has been ignored for a long time.
