I am not American, so correct my views maybe:
Indians (I dont know if they accept that term?) or better said, Natives, arent any more native than everyone else today, right?.
The only difference would be genetic, but a white or black or hispanic or asian or whatever American born and raised in America is just as Native as a socalled Native American.
So what is there to give back? They never had what is given back, right?
I might be wrong here of course but I am not so sure about this.
Its the same here in central europe were today's jews claim money from today's non-jews for the holocaust drama although both sides werent born anywere near those cruel times.
I am not a fan of those things.
