Hi Fg:  first, I think it's more a question of when an individual is in private versus in public.  Second, there are Stats Can data that will be released next week on minority groups in Canada to confirm this, but my understanding is that Moslems make up only a fraction of the Canadian population (3.2% at last count), and that only a fraction of them choose this garb.  We have a population of 35 million, so they're not likely to assimilate the rest of us any time soon (if that's a real risk, we're more likely to end up as Tagalog/Spanish-speaking Roman Catholics, just going by the numbers...).

And why is this 'wrongness' that requires intervention and coercion by the state, other than the fact that it makes you uncomfortable?
