In an interview with Barbara Miner, included in Rethinking Columbus, Suzan Shown Harjo of the Morning Star Institute, who is Creek and Cheyenne, said: “As Native American peoples in this red quarter of Mother Earth, we have no reason to celebrate an invasion that caused the demise of so many of our people, and is still causing destruction today.” After all, Columbus did not merely “discover,” he took over. He kidnapped Taínos, enslaved them—“Let us in the name of the Holy Trinity go on sending all the slaves that can be sold,” Columbus wrote—and “punished” them by ordering that their hands be cut off or that they be chased down by vicious attack dogs, if they failed to deliver the quota of gold that Columbus demanded. One eyewitness accompanying Columbus wrote that it “did them great damage, for a dog is the equal of 10 men against the Indians.”

Corporate textbooks and children’s biographies of Columbus included none of this and were filled with misinformation and distortion. But the deeper problem was the subtext of the Columbus story: it’s OK for big nations to bully small nations, for white people to dominate people of color, to celebrate the colonialists with no attention paid to the perspectives of the colonized, to view history solely from the standpoint of the winners.

I’m not the least bit sorry that my office doesn’t recognize Columbus Day. It’s a dirty holiday and I’m disgusted that textbooks still treat him like some sort of hero.
