Wait until the indigenous folks start going back further in time and revising their own conquests. That should be fun to watch. Oh, and they had slavery too, in case where their enemies weren't exterminated outright or even eaten sometimes.

Quote from Wikipedia: "Native American groups often enslaved war captives, whom they primarily used for small-scale labor. Others however would stake themselves in gambling situations when they had nothing else, which would put them into servitude for a short time, or in some cases for life; captives were also sometimes tortured as part of religious rites, and these sometimes involved ritual cannibalism."

And when Europeans arrived, natives held African slaves, too, as well as sold their own _native_ war captives to Europeans, much like Africans did in Africa. I wonder what they think of the idea of "reparations". But I digress.

So when someone says that Mount Rushmore belongs to the Lakota tribe, if we aren't willing to let the sleeping dogs lie, other tribes might want Lakota to revise that statement. Unwind it far enough, and who knows what tribe settled there first (assuming it even exists nowadays).

Cursory search suggests that Black Hills (now Mount Rushmore) was first settled by Arikara, and then, quote: "The Arikara in the Black Hills was followed by the Crow, Pawnee, Kiowa, Cheyenne, Lakota Sioux, and then to the United States. The Lakota Sioux arrived in the region after getting kicked out of Minnesota in the late 1770s by other tribes. The Sioux took over the region after they drove out the Cheyenne Indian nation. The Sioux forced the Cheyenne to move West."

So yeah, if we're going to unwind, why stop at when the United States took the land. Let's unwind all the way.

Or maybe, just maybe, the SCOTUS decision was idiotic.
