Geez, Ross....
..that's the most ridiculous trail of reasoning I've heard from you. Please note that if Columbus hadn't made his voyage.... someone else would have. It was inevitable that the Americas would be discovered.... and that the riches of the new world would be coveted by others. There was no Greenpeace, Amnesty International, Peace Corps, United Nations, World Banking Org. or any International law protecting indigenous societies from invaders in those days. Why don't you blame the Normans, the Saracens, the Romans, the Huns, the Monguls, the Macedonians, or any other conquering civilization for the European mentality that resulted in colonization.Like a previous poster said, columbus' voyage is significant in that it led Europe out of the dark ages into The Age of Discovery and the Renaissance. Your native americans came here by a different route, Siberia I believe, and they have a history of violence as vivid as any other culture from Europe, Asia or Africa. For me, I've never given much attention to Columbus Day... because it's always been more a celebration of Italian heritage rather than a tribute to sailing and navigation.
