Over at American Greatness, Mackubin Owens attempts to bring reason, context, and actual history to the Columbus Day debate. I found this part to be especially important
The flip side of the denigration of Columbus and the United States is the claim that the native peoples of America were peaceful and innocent victims of white greed and violence. The fact is that the Indians did the same things to other Indians the white man is accused of having done to the Indians.
They fought over land and hunting grounds. They fought over trade with the British and the French. The Iroquois, who allied themselves with the British during the colonial period, fought a war of extermination against the Huron, who allied themselves with the French. For accounts of the interactions of the Europeans, Americans, and the various Indian tribes, read Francis Parkman and James Axtell.
Atrocities by one tribe against another were a matter of course. Many of the tribes practiced ritual torture. An observer provided an account of Iroquois warriors burning Huron captives. As the flames consumed them, the Huron sang a song. “It was a very sad song,” the observer noted.
Lots more at the link. Any meaningful debate of history, and historical figures must include context, and facts, period. The leftists, of course want nothing to do with that. To them, this is all about destroying American, not imparting historical knowledge.
