No, I don't think I disagree with you.
I'm fairly certain we'd find a correlation between wahabbist and desecration.
I'm not sure we'd find a correlation between wahabbist and rioting auto torcher, but I think we will.
We'd have to have a broad enough sample to measure at least these two groups: french muslim wahabbists and french muslim non-wahabbists.
Many frenchmen have been unemployed lately, too. The economy has been down for more than a few years. There were no riots and cars torched. Why riot and why now?
You could say the same thing about riots in the U.S.
The key point, in my opinion, is not simple unemployment, but the existence of a permanent government-dependent underclass.
