BTW, I think you'll find that the vast majority of the world does not agree with your "one people, one big nation" idea. It isn't the governments and it isn't just bigots who believe this, although it's a good way to demonize and discredit those who don't agree with you.
Most of the wars being fought right now in the world are being fought because one ethnic or tribal group doesn't want another ethnic or tribal group running their lives and telling them what to do. This is not because they fear them because they don't know them. It's because their sense of identity is bound up in their ethnicity and they want that preserved.
If this is not valid, then you should be working to get Native Americans to assimilate as quickly as possible and become part of the "one people" instead of a distince group.
