Most of these guys are on a state of mental disarray because they see clear through the system we have in Europe. It's a hell of a life, granted better than what they could have expected had they seen the light on their "home" countries, to live when you are continuously confronted with the filthy sight of social stagnation and rejection. They cave in easily and can't cope with it. While you seem pretty much adamant to accuse Islam
by deflection, I'd be far more cautious on that, since we had not so far other similar issues with social disparity. It was called class warfare. While everyone buried Communism, they all forgot that communism was a reaction. A fairly constructed one, but yet a reaction. And before communism, France had a Revolution. And before that a Religious conflict. etc etc etc. Class warfare just got a "djellabah".
