I think that one not only has to make demands on the established group, but one also has to make demands on the outsider group. One has to make clear: if you want to leave, please do so. But if you want to stay here, a degree of accommodation to the Dutch outlook, Dutch manners, and a degree of identification with the Netherlands will be expected of you. There is no reason why there cannot be Dutch Turks or Dutch Moroccans. But one can expect from them a degree of identification, some change of their own social identity.
