Wilma Mankiller said this quote

Though many non-Native Americans have learned very little about us, over time we have had to learn everything about them. We watch their films, read their literature, worship in their churches, and attend their schools. Every third-grade student in the United States is presented with the concept of Europeans discovering America as a New World with fertile soil, abundant gifts of nature, and glorious mountains and rivers. Only the most enlightened teachers will explain that this world certainly wasn't new to the millions of indigenous people who already lived here when Columbus arrived.
