Oglala Lakota journalist Tim Giago says Stop trying to rename ‘Indians’. Giago’s whole essay merits your time, but I especially liked this paragraph:
I am a firm believer that most historians are wrong when they credit Christopher Columbus for coining the word “Indian” because he thought he was landing his ships in India. In 1492 there was no country known as India. Instead that country was called Hindustan. I think that is closer to the truth that the Spanish padre that sailed with Columbus was so impressed with the innocence of the Natives he observed that he called them Los Ninos in Dios. My spelling may be wrong on the Spanish words, but the description by the padre means something like “Children of God.”
