I don't believe that "expert" for one second. How the f**k does a community of people establish sovereignty within a state? That's a ludicrous notion. As for Muslim communities not trying to integrate, that's an issue with most immigrant populations. Here in Canada, libtards keep preaching on and on about having to let immigrant communities do things their own way. Truth is, if you're going to move to a new nation, that means your lifestyle is going to change and you can't expect to live the same way here that you did back home.
