So presumably, if some foreign power invaded the US next week, violently exterminated most of the population, and herded the survivors into a few tracts of land, you would be fine with that? After all, land changes hands continuously.
All I'm asking is, would it be any major abberration, considering human history? Or would it just be: after atrocious violence and savagery, land briefly under the control of vague human entity X now seems to be under the control of vague human entity Y, episode #37,093,840?
Well, except perhaps the debate over that native american reservation that the federal government is currently seizing to hand over to a coal mining company.
Moreover, if there was official recognition of what really happened, even now much could be done to redress the original injustice and give these people some closure. Instead, schoolchildren are taught a sanitized version of American history which really adds insult to injury, from the point of view of the surviving natives.
So? In a day, a modern celebrity can influence people with a "speed and thoroughness" that would be totally unthinkable to a Jewish celebrity 2000+ years ago.
... But that's due to technology, not due to the differences between Kim Kardashian and Jesus.
In 500 years, the bloody Annexation of Sol is going to be exceptionally speedy and thorough too, because it's easier to be speedy and thorough when you've got warp-drives and teleporters.
The scale of the forced displacements is literately continent scale! Its probably the biggest settler colonization in history. Compare with the colonization of South America, where the Spaniards aimed to use the existing population for labour, and thus gave them some rights and allowed them stay. Or Africa, where the Colonial powers basically conquered for labor and not for land to settle.
I don't know that the pattern of forced displacement has ever occurred on this scale, and with so high compression. Usually when people are forced from their lands, there are some crappier lands somewhere else they go to. From the map this obviously was not what happened. The tribes where forced into extremely small areas over the course of just a hundred years.
I can tell you that I wouldn't expect to stand on my doorstep, facing the men with guns, saying, "ah, ah, ah, I own this land!" and have them turn away.
We do horrible things to other people, no doubt about it. Even worse, this specific moment in history isn't unique. So it goes.
