"Would there be the slightest fuss if some nun with a veiled face wanted to board a bus in Quebec? The question answers itself."

LOL! Does it? Um, no. You obviously know little about Catholicism or Quebec.

First, not only do nuns not cover their faces, it has been decades since they wore the traditional habit with the full veil and skirts to the floor. They adopted a more normal habit in the 60s, precisely so they could better relate to the population. A wide smile and open face is part of the image they want to convey.

But even that hasn't been enough to get the Church back in the good graces of the population, and religious orders and priests tend to keep a low profile.

Quebecers are proud of having gotten the Church out of public institutions, and see Islam as Catholicism on steroids.

Which does not mean they are not attached to their culture, which was based on Catholicism, just as secular Jews or secular Muslims can still be attached to their cultures.
