OK, so an interesting point is brought up. The land isn't ours. It belongs to the native people. Seceeding and creating a land that strives to treat every human being as what they are, inherantly equal, isn't doing a lot for the native people. But it must also be admitted that staying part of the united states is doing nothing for the native people. Obviously we would contact native people of this land and ask for their permission and hopefully support on this, and I can't begin to see why they would say no. There's plenty of land, plenty of resources for coexistance. Beyond that, no longer being given land and given rights would be a step in the right direction.
The rights are theirs, the land is theirs. That has always been true. But now the inhabitants of the land are about sharing and coexistance instead of theft and genocide.
True we have no plans to come through and heroicly save the natives of this land, but wouldn't it be racist to take it upon ourselves that they need some mostly (though not entirely) white heroes to rescue them from their problems.
