““For realists, the true story of the Civil War illuminates the problem of ostensibly sober-minded compromise with powerful, and intractable, evil. For radicals, the wave of white terrorism that followed the war offers lessons on the price of revolutionary change. White Americans finding easy comfort in nonviolence and the radical love of the civil-rights movement must reckon with the unsettling fact that black people in this country achieved the rudiments of their freedom through the killing of whites.””
