Why are French Muslims rioting?

Try Jane Galt, who this morning did not play Civilization.  She starts here:

Muslim youth are rioting in France because breaking windows and setting cars on fire is fun.

Everyone who has ever taken their .22 out to the back forty and shot up a line of old bug spray cans knows this. Seeing things break, disintegrate, or explode, at absolutely no personal risk to yourself, lights up some primitive reptilian part of our brain with searing glee. I’ve often thought there would be big money for the firm that figured out how to build an adult recreation center where frustrated Americans could go to have a beer, take a sledgehammer to a used computer, and throw some glassware at the walls.
