The whole premise of the Indigenous People’s Day is that Columbus caused death, disease, unrest, and pain in the lives of native Western Hemisphere peoples. Of course, that premise, like most Liberal ideas, is based on a utopian LIE!
The natives of the Western Hemisphere were not sitting around singing love songs and living forever before Columbus set foot here - there were wars, disease, famine, cannibalism, pain, and unrest occurring from one end to the other here before Columbus was even born!
Columbus Day is not a slight to the Indigenous people of the Western Hemisphere. It is a remembrance and celebration of expanding cultures and seeking new horizons. Much like our Independence Day celebrations are not a slight to Britain, they are a celebration of our success.
My short list of links to show how lovey dovey the Indians were toward each other before the white Man arrived.
