I might be off on this, but my recent thinking is along these lines:

• Landback is a component of the (american) indigenous liberation movement.
• The indigenous liberation movement is one of several decolonial movements.
• decolonial movements are closely associated with anti-imperialism, and both of those have a lot of association with socialism.

As a socialist living on occupied land, I believe it is imperative to build socialism here, while also working toward decolonizing our land (or reasons of justice, sustainability, anti-capitalism etc… the list goes on…). As we know “white people leftism” is prone to decay into social-fascism/liberalism unless it is grounded in some sort of third worldism/anti-imperialism/ or decolonialism (most straightforward in my opinion.

Like so many questions osurrounding social justice, it is my belief that a socialist future makes it much easier to address these topics head on. Liberal solutions under capitalism are just patchwork solutions that are not sufficient nor sufficiently robust.

I feel like I am still working through this thought process. I am caught between “under socialism we are going to eliminate all these injustices” which is true, but I also can’t “all lives matter” the specific work that needs to be done to liberate our indigenous comrades and other communities who have been crushed by capitalism harder than my settler ass. These things go hand in hand while also providing a sufficient grounding (literal grounding on the land itself) to prevent liberalism within the socialist movement.

I hope for a future without oppression, marginalization, and injustice where there is not a significant difference between settler and indigenous, nor will there be an oppressor/oppressed class. Likely will happen beyond my lifetime, of course.
