Fair enough. My opinion is that Indians got a raw deal for hundreds of years, so I'm OK with them having a special arrangement, which derives treaties signed by our government long ago.
So what? You could say the same thing for the native britons under the saxons, or the saxons under the normans. Or everyone under the romans. Do they all get preferential treatment? Who does not have ancestors that were oppressed at some point? More importantly, has anyone living today oppressed the indians? I know I haven't.
Just how raw a deal have the indians gotten under westerners? Yes, there have been deplorable incidents and policies, but think on this: before Columbus, the indians were still living in the stone age. Sure, some had advanced cultures, but what did most of those advanced cultures base themselves on? War, enslavement, human sacrifice, and other despicable acts. The aztecs were doing well before the spaniards came on the scene, but what about the tlaxcala under the aztecs? Sure, some horrible westerners gave indians blankets infected with smallpox, and that was one of the most evil acts possible. But without the westerners, modern indians wouldn't have penecillin. Without westerners, indians wouldn't even have horses and would still be subsisting by chasing buffalo over cliffs.
My point is that history is full of human interactions and migrations that were either harmful or beneficial to other humans. You can't place blame on modern people for those acts. We are not guilty of the sins of our fathers.

But in theory, all men (and women) are created equal. Injustice cannot be corrected through more injustice.

Then we honor those treaties. Which means, I believe, that indians are entitled to do whatever they want on reservation land. There is nothing in any of those treaties about granting indians the privilege of building casinos in non-reservation land where the average citizens is disallowed from doing so. When they leave the reservation, they abandon any privilege granted to them, and must be subject to the same laws as everyone else. Anything else is unfair and unjust.
