An ugly part of American history to be sure.
BTW you have a sentence fragment, or so it seems: "It wasn't until the Wounded Knee Massacre in 1890."
Fixed.
Well, I do think that great saint and church doctor of whom I'm something of scholar on -- Saint Augustine -- said it best; the city of man is moved by the lust to dominate and is itself dominated by that lust.
Fun fact, Cain's name in Hebrew means possession/control (e.g. to dominate) and Enoch means dedication. Given that it is the Cainite line that founds the cities of the world in Genesis, Augustine's allegorical reading asserts that the city of man is dedicated to the lust to dominate! How right, how right he is!
