I don’t think it’s a bad example in this case, since the US hasn’t lost it’s own cultural heritage much. For better or for worse, the US does a great job of assimilating people and making them “American”.
That’s pretty much exactly what Quebec is trying to accomplish, right? something like ‘if you want to live in Quebec, you have to become Quebecois’. So if US policy doesn’t blanket ban other languages in signage and social services and still manages to ‘americanize’ people, then Quebec could potentially do the same.
The US and Quebec are in pretty different situations, so it’s not a perfect example, but I think it is a pretty good basis for an argument against Quebec’s culturally protectionist policies.
I wont comment on the efficacy of the search itself—I don’t know enough to meaningfully hold a stance about it—but I think you also have to consider the symbolic meaning of the government funding this search. There’s a long history of federal and provincial governments at best ignoring indigenous people and their struggles, if not actively pursuing policy that harms them.
This search has become a flashpoint for an accumulation of unrest over that history, it can’t be viewed in a vacuum. The sheer poetic horror of murder victims rotting in a landfill makes this example particularly abhorrent, but it’s hardly the only time the police and justice system has failed indigenous women and girls. The government putting a lot of funding into this specific search is bigger than just the outcome of the search itself.
