Yes you could say the same thing about them, and I would be completely sympathetic to indigenous people in Quebec promoting the use of their own languages in their own territories, and discouraging the use of French. Unfortunately some of the groups have so few members (like the 600 you point out) that it would be difficult for them to be viable as a modern civilization using only their native language, but if they are somehow able to do so, that's great and I hope they succeed.

I explicitly mentioned in my comment that the destruction of indigenous cultures throughout the Americas was a regrettable thing, which is why Quebecers would like to avoid it happening to themselves.

I'm not blindly arguing here that French is the greatest language ever and nationalist Quebecers are correct on all political matters. I think French people were colonialists and their treatment of Native Americans in Quebec was terrible. But that doesn't change that now, however unsavory the circumstances of its birth, the Quebec culture doesn't deserve to be wiped out.

I don’t think we even need to entertain discussion of the idea that any culture should be wiped out. That’s a non-starter. The distinction here is one of political power.

Francophone Quebecers have enough political power to enforce and expand their language and culture laws in order to “defend” their culture. But never lose sight of the fact that this comes at the expense of more than just anglophone residents. This affects all other cultures within Quebec. And that’s why you see it take the form of more than just language, it includes attacks on minority religious symbols and clothing as well.
