"The second solution is communitarianism, also baptised assimilation. It is a question of a compromise, inspired by the United States and rather unclear theories of intellectual ‘ethnopluralism’, Right-wing and Left-wing. People born abroad keep their ‘culture’, but adhere to a common ‘minimum’, a global Social Contract. Society becomes a pacific kaleidoscope, united by a soft and pacifying deus ex machina. This utopian vision, Rousseauian and adolescent, still defended by learned old fogies, who flirt just a little with apartheid (whence its partisans on the extreme Right) has been tried by all the European states. The result has been total failure. There has been no ‘assimilation’ of ‘ethnic communities’ cohabiting peacefully. On the contrary, ethnic civil war is just around the corner."
