In 1492 Columbus declared that the Native Americans or Indians were an inferior race.
1n 1942 U.S. government press release said 40 percent more Native Americans have enlisted to fight in WWII than have been drafted. Altogether, 25,000 Indians served in the U.S. armed forces, including 800 women. In the Philippines, a Choctaw scout escaped from the Japanese at the battle of Corregidor, and led underground guerrilla forces until the war ended. The Oneidas, Chippewas, and Comanches blocked Japanese decoding of military information by dispatching messages in their tribal languages. Navajo Code Talkers were instrumental in the landing at Guadalcanal, where they sent and received reports from field commanders.
It just goes to show you that first impressions are not always the best or correct impression and it is good thing to learn more about any group of people before you label them as "inferior."
