I agree with this sentiment. Also, "indeginous" people have fought each other over land, taken over land, lost land etc, especially in largely tribal areas.
(American Indians, Mongolians, Barbarians, Romans, Greeks...Muhammed...) To call one group of people the sole settlers and owners of a piece of land is ludicrous. What about the people there before them who were outed more than likely militarily?
All people in all regions through out time have fought for and either won or lost land. Europeans had the dominant military and culture compared to others during the discovery days.
They fought for and won the land just like the "indigenous" people before them and then maintained it. Other europeans fought for the same land and won too. (American Revolutions) and now own the land first settled by the brits, french and spaniards.
The world works by rewarding the winner. If an indeginous group loses to the new kid on the block, he is shit out of luck and would have done the same to further his own progress had he been adequately armed and ready.
Europe and it's offshoots still have the dominant hand politically, economically and militarily. Our system obviously works better than "their" system and has done so for hundreds of years. Otherwise, the world would be shaped completely differently.
The spread of our culture is socio-political evolution. Until something stronger and with more widespread backing outs us, we will dominate and progress as we are. With the world growing as it is cultures will blend, co-exist and be eliminated.
If one culture wants to test another rather than co-exist (9/11 for example), one will win and one will lose. When a culture draws a hard line at intolerance for another culture (fundamental islam for a much more liberal "west") a fight will undoubtedly break out. We are winning. So be it.
