The Muslims in Europe do seem unusually violent, at least in comparison to the ones in Dearborn, Michigan, and other nearby areas.
They are more violent, but the surprise is the sharp contrast between the current European Muslims(age 30 or so and below) and the previous generation. Several factors have contributed to this. When the previous generation came here they integrated into our society. This led to a development of nominal-Islam. The parents would bring thier children to the mosque, but nothing else. Since the parents weren't really into Islam and wouldn't become imams, the Muslim community imported all of thier imams from places like Saudi Arabia and from radical schools that weren't necissarily accepted even in some middle eastern countries. So most of the imams found in the mosques of Europe were now radicals. So the kids that were going to mosques came into contact with this reactionary fascist thought and bought into it. This continues to this day. There are also reasons why French muslims are the most violent, but I won't go into that right now(unless you want).
