It's the lie that is promoted by the mentality ill. Some part of it might be true, but it's in a context which is false or some grand scale that didn't exist. For the record, I am glad there is still claims processes for specific instances but most of the Indians were compensated, they just didn't understand the concept of land ownership and what fair market might be. They got hooked on the juice i.e. goods. There were issues even in the time of the U.S. and I hope everyone was compensated as much as possible, although bring life back is impossible but let be honest.... this was not at scale. The Indians basically sold off their land before the U.S. was a thing.
The thing that I am glad the U.S. has been trying to right for 80 years is the Japanese Americans held in camps during WWII. Some of the people are still alive and there exists a clear taking by the U.S.
I also get a giggle out of people defending Indians, they were always at war with each other and would be considered butchers by today's standards, and even back hundreds of years ago.
