When the BBC covered a "sample" story, they got an attractive young Syrian woman who did not dress in sharia-approved clothes. You thought, well, of course, as long as there is room in the host country's quotas. The idea of the segment was that this what they are like. Really? Yet in the background were more of the real situation. The multiple wives with their children; the angry younger men.
All those European countries need to demand training in pluralism, and I don't know how they would do it or if they know enough about it to matter. They are hardly Christian countries, but if they don't enforce pluralism right from the start, they will disintegrate into unmanageable trouble. They need to tell Muslims that they are coming from a religion that does not know or honor pluralism, and that they will have to change. If they do that, there's a chance.
Islam is not a "religion" as we know it to them; it is the only view of life.
