"Disingenuous" is unfair. But symbolic, certainly. What this is
really about, what I'm getting at, is that this is being done because no one actually gives a shit about the tribes, except the tribes. The state is more or less free to steal from the tribes, or endanger them. If anything of value is found in whatever land they have left, it's taken from them.
So this is symbolism. Standing in front of a bulldozer and saying "NO" is all they have left.
