white anarchists in North America don't stop being settlers because they showed up to Standing Rock and do their best to be in solidarity with anti-colonial movements that are ongoing. I refer specifically to those anarchists acting in good faith. Frankly, I disagree with anyone of any background who says otherwise, I'm skeptical of white people who articulate this, and I'm pretty sure there are at least a few indigenous comrades who share that perspective in all three places you mentioned. But beyond that, it's just how I am defining the words.

don't get me wrong, doing solidarity as a white person is a good thing to enact, but anyone who is part of a settler colonial society is a settler, there aren't moral hierarchies of settler & not-settler depending on your politics. It's just a description of fact: if you are part of these societies, were raised in them, etc, then you are benefiting from settler colonialism by being a settler.

That's kinda ridiculous.
