I would accept that answer if we were talking about the mother tongue, but not when it has to do with learning French. Everyone can learn French.
In my riding, some new immigrants speak three languages: English, French and their mother tongue. I am talking here about young people. The older people often barely speak English and French. But the young, 19-year-olds from Armenia and Maghreb or anywhere else are impressive. So people can learn three languages. It's not the end of the world.
