Alice Walker criticizes the way white women and men had consistently been portrayed as delicate and beautiful in the same way as a white writer would portray them. It was for this reason she first came to appreciate the white author, Flannery O'Connor, who portrayed her characters realistically. White women aren't beautiful simply because of the color of their skin. Being white doesn't automatically make a person beautiful inside or out.
Walker then notes that the three, black female novelist of the 19th century didn't write about black women.... and followed "a black man's interpretation of white, male writers' fantasies." She criticizes the way author, Wallace Thurman, presents his black, female heroine as having no hope because of the color of her skin.... someone who sees the color of her skin as unnatural. Walker critizes this portrayal because of the millions of black women who are content and happy as black women.
