What is the theme in Collected Stories of William Faulkner by William Faulkner?

Racism and prejudice are two ideas that are often addressed in Faulkner's short stories. Slavery is one instance in which the idea of racism comes into play. The story "Red Leaves" gives an interesting view of slavery as it is told from the viewpoint of the Indians. Unlike the white men, the Indians find their Negro slaves troublesome. They often trade them with the white men for horses. Racism is also seen in an interesting view in the story "Mountain Victory."
