To be part of such a group makes for bitterness -- if you let it, we are all individuals and nobody really owns the land -- -- that said, man has been outmoded by invaders since time immemorial and it ain't gonna ending any time soon -- it is now politics -- but the "white" European will soon be displaced in America by Hispanic / Latino heritages...perhaps...which means the "indigenous" tribes/nations [modern term] will be twice removed -- but were there tribes in the Americas before the tribes you speak of? Probably -- It is highly unlikely the America was without people for a million years -- so where do we stand now?
