What language are we speaking?

‘Passe-moi un napkin, s.v.p.: or, pass me a serviette, please?’ Like, what language are we speaking, anyways?

I keep wondering what, if anything we're wasting our breath on arguing over this old English/French thing. I look at people like Pauline Marois and the P.Q., as well as Gilles Duceppe and the Bloc Québécois, and I have to ask myself: Just what or who's under threat from whom?
