Laws that forever affect only one portion of the population, should be illegal, full stop. We should have equal freedoms under law.
And have the U.S. break all treaties recognizing the special laws that apply to Native Americans?
Yeah, not going to happen. I don't even see how it's a worthy goal.
Even so, your view appears to be that that US must not pass new laws that grant Native Americans more self-determination than they currently have.
