I was reading about the French bishops' response to the riots over there in France. They were denying that the riots were organized or were spurred by religion.
On the latter point, I would agree that to some extent that religion is not the cause of the uprisings, but it is one of the causes. Islam is as much an identity for those groups as being Algerian or Moroccan. After all, Islam has throughout its history been a means of overcoming ethnic differences as Muslims have united in common cause.
On the former point, these guys were using cell phones, instant messaging and had organized Molotov cocktail factories, real signs of unorganized activity.
