Fuck the Colonists

https://native-land.ca/ is a good start, for all the tribes and groups that are still around with organizations.

As far as how decolonization proceeds, it's ultimately up to those groups, and no one else.

I’m not an expert or anything, but my understanding is that currently indigenous groups are fighting for land in the court systems as much as that is possible. The goal I’ve heard is most/all land of North America given back to First Nations in a sort of interwoven confederation, not balkanization. Once a dictatorship of the proletariat is established it shouldn’t be too hard to reallocate land from large private landholders and the government. I’m relatively new to the idea too, so I suggest the Decolonized Buffalo podcast on it. The revleft podcast family also might have some stuff on the subject.
