What is it that you want done? Make the Indians "just like everyone else"? I told you, get your elected representative to sponsor legislation to do that. Their status is the result of treaties between them and the federal government. The state can't simply tear up those treaties because they want more revenue. That's the real issue here. The state sees a potential windfall and is moving to grab it.
If they tried the same thing with the churches you'd be up in arms about it, and rightfully so, but because it's the Indians, whom you don't seem to like very much, you take the government's side. Your conservative ideals are taking a backseat to your personal feelings towards those people.
