Well one of the Radical Republican heroes, Thaddeus Stevens, made a speech where he advocates the elimination of the southern race. So I guess we should be glad that the heroic Northern victors managed to stop themselves short of genocide, as appealing as the idea appears to be to their progeny.
Thaddeus Stevens was quite a piece of work. The fact that the officers leading the Confederate raid against his steel mills were able to restrain their men into burning only the steel mills and not the worker’s housing and his own family housing while they were at it speaks well of the disclipline and respect the men had for their leadership.
