Let’s be blunt. White Americans historically did some real bad things to Native Americans.
But Native Americans also did some real bad things to each other. For centuries. Also without the USA, the Nazis would have won WWII. Imagine Nazi mechanized infantry vs. people riding horseback and using primitive weapons. The Nazis would have simply exterminated the Native Americans. Also, more people of Native American descent are alive now than ever in their history.
History is not simple or clear cut. But could people (not referring to most Freepers) learn some basic history?!
My short list of Indian warfare before the White Man arrived.

Without the US joining WWI, the Germans would have won...so there would have been no later Nazi takeover of Germany. But it’s impossible to imagine what Europe would have been like in the 20th century if the New World had never been discovered (or did not exist). There would have been no potato famine in Ireland in the 1840s because the Irish would have not been growing potatoes.
