At any rate, I shall not argue either pre-war Southern attitudes to black or Northern ones, and neither will I decide whether slavery was the worst offense in American history or merely a poor idea.
I will say that the Federal means of ending slavery was terrible. It could have hardly been handled any worse. The North used the black man very well, and created conditions of animosity that would impact the South for over a century, indeed, up to the present day. Please click on my screen name and read the quotes from Patrick Cleburne (CSA), and perhaps get one of the biographies on that man. His words predicted what would happen after the war between blacks and whites down to a tee.
In short, it does not matter if you hate slavery or not: the way it was ended was perhaps worse than slavery itself, or at least if contrasted with a gradual ending done by the individual states. The ends shoudl not justify the means, in this case especially.
And lest you believe the North considered the Civil War to be over slavery, consider the plantations the Yankee army maintained, using former slaves who were promised pay-merely promised. Or that the colored regiments were disbanded after the war (when they could no longer incite Southern population anyway), and blacks esentially excluded from the ranks for years. Or just the attitudes of Northern soldiers on why they were fighting.
Thank you
