Columbus Day isn't what it used to be. There's now debate over whether lessons about indigenous peoples (such as those that Christopher Columbus encountered) should replace the traditional lesson about Columbus discovering America. In South Dakota, the second Monday in October is called Native American Day, which students celebrate by exploring that history and culture. Should other schools follow suit? Indigenous groups and their allies insist that Columbus can't be credited for "discovering" lands that were already inhabited, and that he treated various indigenous peoples brutally. Supporters of traditional Columbus Day counter that the explorer's achievement in opening the Americas to Europe is worthy of honoring, and that we shouldn't judge him according to modern moral standards. Is the push to replace Columbus Day excessive political correctness, or are indigenous peoples more deserving of celebration? Tell us what you think!
