Is everyone dumb around here?
Don't answer that.
France has always been a xenophobic nation, however the EU has made it take in far more immigrants than it desires, which caused the Paris Riots years ago. (usual reasons)
I can only imagine that this is an offshoot of that, it doesn't matter if a small thing apparently started it, that just confirms that its getting worse.
The police over there act like the police in America back in the days of segregation.
So respect them if you like, but France is going to end up dealing with a war at some point, if you would like that here, then just leave, social cohesion is bad as it is, it does not need warmongering dicks forcing the issue to explode.
