Not everyone in Québec is a French Canadian. There are also French Canadians in the rest of Canada.

But I'm guessing laïcité is a concept you would like to learn more about before making sweeping judgements? Laïcité isn't perfect, but neither is exemptionism. Laïcité fails people who want to completely freely express their religion, where exemptionism fails those who want to be free from the religion of others.

Have spend time in religious-conflict zones, I'm personally biased towards laïcité. You can imagine Muslims and Jews might want some freedom from seeing symbols of the other's religion in public institutions right now with the ongoing conflict. Similar feeling for Christians, Orthodox, and Muslims after the Yugoslavian wars; or Christians and Muslims in sub-saharan African; or Sunnis and Shias on Yemen; or anyone who's not Deobandian Sunni in Afghanistan.

Exemptionism is great for people who haven't experienced religious persecution. Québécois.e.s feel, real or precived, that they were persecuted by their own religion. This led to the silent revolution, and has a lasting effect of voting in favour of more restrictive, over open, religious freedom laws.

I hope this helps, and of you have examples of which darker skin religions do not get to keep their culture, I would be interested to hear. My own burrough has large Haitian, Jamaican, and Côté d'ivoirian communities; and a fledgling laosian one.

I think you'd have to discuss that with France first.
