I keep reading comments like that and when I do, I think of the Muslims I know and work with who seem to be every bit as much interested in integrating as, say, my wife's immigrant Dutch parents or the parents of the Italian kids I grew up with.  The first generation to come over, in both cases, tended to stick with many of the "old country" beliefs, values and lifestyle.  My wife's parents stayed with the Christian Reformed Church, sent their kids to Christian Reformed schools, ate Dutch food and made trips back "home".  In the Italian community, the elderly women wore black head to toe and covered their heads with shawls.  The children, however, ended up as Canadian as hockey pucks.  This "they won't integrate" routing is old and tired.
