"Vine Deloria in particular was a great influence to me. He was an intellectual and a writer that was, at times polemic, but he asked important questions of non-Indians. By reading Vine’s work, Custer Died For Your Sins, American Indian Policy in the Twentieth Century, God Is Red, especially these early works, I learned about my own questions that I wanted to ask in my work. He also gave me courage to perform and write."
