There are now hundreds of articles from news sources on the Web talking about the fourth straight day of riots in France, and almost all of them bend over backwards to avoid mentioning that the rioters are Muslim. (There are a couple of elliptical references to "unease over tear gas in a mosque" or "meeting with the president of the Muslim community" without exactly explaining why.)
Can you imagine a similar situation involving the Amish or Mormons or Chassidim or Hindus that would not mention the religion of the rioters when they all have a religion in common?
