OK, since most religions, including Christianity, require people to wear clothing, then perhaps the "secular" government of Quebec should outlaw the wearing of clothing.
The point is, people should have freedom to wear what they want, when they want.  If someone who is Muslim believes that wearing a face covering is essential to their personal modesty, in almost all cases there is no harm in that.  When there are specific cases where there is a conflict between the needs of the society and the wishes of the individual, they should be carefully circumscribed to minimize the incursion of the interests of the state on the personal freedoms of the individual.
What's next in Quebec, mandatory hot pants for nuns?
