What is the significance of the Confederate flag flying

The white children's school is named after Jefferson Davis, the president of the Confederacy. Cassie notes that the Mississippi flag "waving red, white, and blue with the emblem of the Confederacy emblazoned in its upper left-hand corner" flies over the white school. This flag is a symbol of segregation and oppression. Flying over the white school, the flag's presence illustrates that the "ideals" of the Confederacy, including oppression of blacks, still exist many years after the Civil War.
