At Least in America They Understand the Notion of Cultural Difference:
The Guardian

...But while many Muslims here looked to Europe in the hope that it might provide a counterbalance to America's disastrous foreign policy, they also look across the Atlantic in horror at the experiences of their co-religionists. There lies the paradox: the country that has done more than any other to foment Islamic fundamentalism abroad has so far witnessed relatively little of it at home. "Europe is not coping well with the emergence of Islam," says the executive director of Cair, Nihad Awad. "It has taken a long time for them to accept that Islam is part of its future and also part of its past."

The different experiences have emerged partly, it seems, because the Muslim communities on either side of the Atlantic are so different. The patterns of migration have differed. A large proportion of Muslims who came to America arrived with qualifications and were looking for professional work. As a result, they are generally well educated and well off. According to a recent study by the Journal of Human Resources, the wages of Arab and Muslim workers in the US fell by 10% in the years following the terror attacks; but they are still better paid and better educated than non-Muslims.
