It’s an immigrant community that refused to integrate into the culture that existed there before them. If that sounds ridiculous it is because this entire conversation is ridiculous.
Wow. Wow, wow, wow, you're in need of a major history lesson, like how the British first basically committed genocide with the expulsion of the Acadia French, https://en.m.wikipedia.org/wiki/Expulsion_of_the_Acadians, and then when they realized that was a collosal fuck up they explicitly put policies in place to not expel the rest of the French in Quebec and deliberately treat them as second class citizens.
The French that founded Quebec where here predated the English that eventually founded the county of Upper / Lower Canada... You might have a misunderstanding of what the term immigrant means.
It is so ignorant of the definition I don't even know how to find common ground.
