how does alice walker use bigotry to describe her life experiences?

Walker is a political person because of the influence of Martin Luther King, Jr. Because she witnessed the legendary effects of his life, and because she learned from him how much one person can actually change the world, she feels obligated to be a voice herself, for her community. She also considers herself a member of the "poor" community, and she argues that many of the same issues facing Black people are also facing the poor in America.
