I’ve already posted today about experiences in France in the early 90s, so this is pushing it. But I note: even then, I noticed great trepidation building among the French regarding the numbers of Muslim North Africans (Tunisians, Algerians, Moroccans) immigrating to the south of France. There was an area in Toulon, where I lived, that you would swear was an an enclave of Tunis. Marseilles? Forget it; hugely Tunisian and Algerian.
On a very side note, this did make for some unbelievably interesting late-night (early morning, actually) excursions to African nightclubs frequented by the more secular Africans. The music, both Arab and African "rock", has a rhythm and beat unlike that to which we’re accustomed. I can really appreciate it, though I digress.
France is getting tougher. To all those libertarians who have trouble with distinctions: if you can peremptorily kill them for issuing a verbal threat on your life (assault), you certainly can expel them from your midst and it hasn’t a thing in the world to do with "free speech."
