"A word from Lee might have encouraged white Southerners to accord blacks equal rights and inhibited the violence against the freed people that swept the region during Reconstruction, but he chose to remain silent." Lee was also urged to condemn the white-supremacy organization Ku Klux Klan, but opted to remain silent.
