There was no immediate claim of responsibility, and the identity of the driver was not immediately clear, but the Nice Matin newspaper reported early Friday that he was a 31-year-old Frenchman of Tunisian origin. [Archive.is. link]Does that mean a first generation immigrant, born in Tunisia, or a Tunisian with French citizenship because he was born in a Tunisian neighborhood in France? I don't know, but whatever it means, it doesn't mean a "Frenchman" in the way that term is understood by (a) the French, and (b) native speakers of English.
France is much more of an ethnostate than the US, Canada, or Australia. It makes sense to speak of someone of Arab descent born in Detroit as an American—it doesn't make sense to refer to someone of the same ethnicity born in a suburb of Paris as a "Frenchman." We've been explaining it here for fifteen years—see Racial Gangrape: Another Diversity Disaster, by the late Sam Francis, August 9, 2001
Back in April, 11 young black males went on trial in Paris for the gang rape of a 14-year-old white girl seven years ago. Rapes happen all the time, of course, but this one was unusually notable. It turned out to be a ritual for initiation into a gang. (VDARE.com note: The Guardian story on this case refers to the rapists as “French youths”. See Peter Brimelow`s review of Paved with Good Intentions for a discussion of this media phenomenon.)
