Colonization imposes dominion and its own views on other ethnic groups because of greed and intolerance. It presumes that the oppressor is superior, knows what is best and is entitled to impose change on those it cannot relate to.
This "fit in or else" principle is still applied today in our "civilized" world (even at the domestic level).
Compulsion to control is the central issue.
Isn't it what much despised " Islamic State" is also trying to enforce ?
Sure, among more "advanced" cultures, suppression and repression go on in a less "in your face", brutal manner but the underlying principle is identical. In spite of being implemented in a more covert, insidious manner, its aim is the same : taking over of land and resources, eradication of existing values and imposition of a way of life upon others, regardless of the fact that it is irrelevant to them.
Cruelty and intolerance have many faces, some bare, others masked.
