The French do tend towards language chauvinism.
No, sorry but that's simply not true. The French language nowadays includes a lot of foreign words. Of course we have the French Academy which tries to impose French words for everything but really, these (generally old) guys are representative of themselves only, and have nearly no relevance. For instance, they tried to impose "couriel" instead of "email" (and a whole bunch of other ridiculous words) but hey, who would have guessed, it never picked up
I believe French-speaking Canadians, OTOH, tend to be much more protective towards the original language.
