I'll just quote this bright man here but I think it's a big enough post that most arguments and interrogations will find a reply or an answer.
In truth, I think it stems from some misguided fear that allowing Muslims into the country will result in their children being converted, or some such nonsense, further eroding traditions.
Why is it illegal to walk around naked? Isn't that the same rationale as allowing PDA, or allowing women to breastfeed in public? Don't look if you don't like it.
Why is it illegal to have sexual relations with close relatives? Assume both are consenting adults and use protection rigourously. Why should the State care what goes on in the bedrooms of consenting adults? In the same vein, why is polygamy illegal?
Why is it illegal (in Canada) for adult and consenting females to undergo FGM beyond the mere ceremonial pinprick? Isn't it their body, their choice?
In answer to your previous (and oft-repeated by others) statement of "I don't see what the ban achieves", the answer depends on what you mean by "achieving something". If you mean that "something" is freeing unwilling niqabis from cultural pressures to don the full veil, or persuading willing niqabis to suddenly accept Western values wholesale and ditch the veils out of their own free will, then it will achieve next to nothing. I'm not holding my breath, none of that will happen. Hate speech laws don't keep racists from being racists.
However, I think a society has the right to decide for itself which behaviours and values are acceptable in public life. We've got plenty of examples in our law codes, that's just one more. Here we have a garment, whether it's religious or cultural doesn't really matter, that has profoundly disturbing connotations in Quebec society. The premier himself, a Liberal, has noted that the niqab symbolizes "l’instrumentalisation de la religion pour des fins d’oppression et de soumission" (the instrumentation of religion to ends of oppression and submission). That is the connotation the full face veil has in Quebec.
Consider that secular Quebec is a relatively young entity. You are close to something with your "fear of being converted" comment, but you haven't scored bull's eye. In living memory, the Catholic Church had nigh-absolute dominion over my province's society and government. For all intents and purposes, Francophone Quebec was a theocracy. When a mother gave birth and there were complications, it was the parish priest who decided which to save - the mother or the child. It was always the child. Women were subjected to routine visits by clerical authorities and "encouraged" to have more children, even in cases where it was medically known one more birth would kill the woman. We didn't have Ministries of Health or Education until the mid-60s - until then, schools and hospitals were ran by the Church. And finally, and perhaps the greatest injustice of all, the Catholic Church in Quebec made it almost impossible for French Canadians to have any chance of social mobility in their own society - except through limited professions like law or medicine and of course, the Church. We were hewers of wood and drawers of water in our own society, our women sows for the agrarian, fundamentally Catholic utopia of the Church, we were "nés pour une bouchée de pain" (born for a bite of bread) as the saying goes, until the
Quiet Revolution took place.
Put simply, the Quiet Revolution is when we realized that we were better than we thought we were. We took control back of our society and government from the Church and its secular agents. Notably, when we created the Ministry of Education, we gave the teaching nuns a choice : take off your cornets and keep teaching, keep them on and retire to the nunneries where you belong. See the parallel?
We're not scared of being converted. We're not even Christians for the most part. We don't marry in the Church. We don't baptize our children anymore (mine was the last generation where this was mostly done as a matter of course). We don't go to Church. We'll say we're "Catholic" because of some vague attachment to the cultural aspects of Quebec's religious legacy - remember that everything I wrote about above is living memory, and the toponyms especially still carry a heavy Catholic influence (if you look at a map of Quebec, you'll swear nearly every town has the name of a saint). Hell, I had religion classes in high school. I'm 27.
So when you think about why there is such widespread support (this measure in particular
polled at 94% support among francophones in Montreal - the biggest and most multicultural city, it's likely higher everywhere else) for a measure that will be for nearly all intents and purposes ineffective, you have to keep this context in mind. Distrust of religion - any and all religion - is a peculiarly Quebecer value. In Quebec, religion belongs in exactly 3 places : your inner life, your private home and your place of worship. You do not talk about it unless you're certain you're with people who want to talk about it. You do not show your faith in public. You make the least fuzz possible about it. If it's really necessary, we'll twist the rules a bit so you can do whatever you need, such as praying - but out of sight and out of mind.
So this ban is just like any other ban based of values - it sets a standard for what Quebec society is ready to tolerate in public. We forbid hate speech because we think sentences like "death to globalist kikes" or "niggers should be enslaved" are repugnant - we can't stop anybody from thinking those things, but we can at least keep them from displaying these sentiments in public. It's the same thing with the niqab, whether it's religious or simply cultural doesn't really matter (and in Canada a simple sincere belief that one has to wear the niqab in the name of religion would count as a religious belief anyway, no matter if that belief is theologically true or not), it's an open display of everything we as a society despise about religion, its dogmas and its excesses. We're not scared of being converted. We're insulted because niqabis are flaunting the most basic rules of "vivre-ensemble" (live-togetherness) we've decided we wanted for our society. They're wearing shoes inside. It won't kill us, we can just wash up after, but we'd rather not and we've the right to set rules in our home.
Do you know Popper's paradox of tolerance? Unlimited tolerance leads to the disappearance of tolerance. So in real terms, there has to be a line drawn somewhere, but that line is at least somewhat subjective. In Quebec, the niqab would probably be largely considered a display of intolerance that we have no business tolerating or normalizing.
Quebec is a distinct society within Canada. We've made the shift from a quasi-theocratical, parochial society of illiterate peasants to a proudly egalitarian, confident and modern society in 60 short years. Our policies on most subjects are some of the most progressive in North America. We also hold some of the French attachment to
laïcité, a concept which, shared language oblige, is known and appreciated here. It's not for nothing a niqab ban (in fact, a harsher one) is in effect in France and Belgium, and in these two countries it has been upheld by the ECHR as valid. Different societies have different concepts of "live-togetherness". It's cool if other societies are willing to tolerate niqabis, but it doesn't make us racists, Islamophobes or xenophobes if we don't. Morocco doesn't seem to tolerate them either.
There are just too few for this to happen. That being said, when you are part of a minority already, like the French are in Canada and the Afrikaner is in South Africa, and the government doesn't actively protect your culture, then it really does get eroded by the dominant culture. The same thing happened to native Americans, for instance. Is this inevitable? Perhaps. That doesn't make it a non-issue.
True. We've survived to best efforts of the British Empire to assimilate us, we can survive 3% or so Muslims. That's not the problem.
Canadian multicultural doctrine is officially rejected in Quebec in favour of "interculturalism" : we're willing to take immigrant cultural contributions in a spirit of mutual curiosity and learning, but otherwise you're expected to adhere to the rules of dominant francophone society. That includes the very Quebecer disdain towards being openly religious.
I've never understood how Anglo-Canadians are so alright with this (to me) extreme "you-do-you" attitude. We are more communitarian - we expect more conformity in return. Think of it as the difference between big city and small town. But that's the crux of the debate. We have different values, we're different societies. I've written this big post but I don't really expect anyone to truly get it.
We could discuss until the cows come home about which values are right or wrong, in all probability no one will change their minds - all I know is that I really resent the attitude of some Canadian politicians who want the feds to come and meddle in our affairs through a Charter that has been forced down our throats and which is left unsigned by Quebec to this very day. We might very well see an uptick in sovereigntist sentiment if this happens.
