I believe it's the wing that acknowledges that any temporary or permanent governmental structure that tries to give all US land back to the Indigenous tribes would probably be beheaded before the ink on the paper could dry, and that much like guns some cats can't be put back in the bag. I think the point of a two state solution would be to return as much land as possible without getting overthrown yourself and allowing these Indigenous peoples to have sovereignty and self-determination, the likes of which they were promised and never got to fully realize. Whether or not they trust that is a different matter, and an equally important one. A true solution would require complete integration of these native peoples into the decision making process to create an equitable solution for everyone where we could hopefully begin to move forward and start the multi-century, multi-generational healing process for these disenfranchised communities. We can't undo the mistakes of the past and we can't instantly remediate things in the present, so we hope to build a better, more equitable and egalitarian future that benefits everyone and does not require sacrifices to our necessities in the name of capitalism.

And I agree that many leftist political and social ideologies resemble many indigenous and aboriginal political and social structures, however in a very different (but still uncannily similar) context. I cannot comment on how much of these writings and ideologies were directly stolen from indigenous or aboriginal peoples, nor what the impact of that is as I am not well-enough versed in every aspect of this. However what I will say is that if we do not take action soon, then our opportunities to prevent further irreversible harm and damage will dwindle.
