Should Columbus Day continue to be celebrated in the U.S.?

Columbus Day should not continue to be celebrated in the U.S. because Columbus was a cruel man who allowed his men to rape, murder, and enslave the indigenous people they encountered. Celebrating Columbus Day would be saying that that was okay. Columbus also didn't really discover the Americas. The Indians did thousands of years before he did. If anything, we should be celebrating "Indigenous People's Day" and not Columbus Day.
