We have to nail down the definition of the problem. There is no general failure to integrate. In the U.K., for example, we are not talking about Chinese or Indians. We are not talking about blacks and Asians. This is a particular problem. It is about the failure of one part of the Muslim community to resolve and create an identity that is both British and Muslim. And I stress part of it. Most Muslims are as much at ease with their citizenship in the U.K. as I am. I dare say that is true in other European nations too.
However, some don't integrate. But when we talk about this in general terms, without precision, for fear of "stigmatizing" Muslims, we alienate public opinion and isolate the majority of Muslims who are integrating and want to be as much part of our society as any other group. Then, because we won't identify the problem as it is, a subterranean debate takes the place of an open one, and that debate lumps all Muslims together. So in the interest of "defending" the Muslim community, we actually segregate it by refusing to have an honest debate about what is happening.
