It would be good for you to know the slaveowners who wouldn't give up their slaves while the rest of the country was ramping the practice down were the worst of tyrannists.
BTW, General Benjamin Butler of the damnyankee army was SELLING captured slaves on the New Orleans slave block in 1863! MOST of the slaves sold were either free men & women OR CSA soldiers, who had been captured. 1/5 of the sale price went to the auctioneer (a union colonel-this is why auctioneers are called colonel today!), 1/5 to Gen Butler and the other 3/5 to the damnyankee army.
face it #3, the damnyankees were ALWAYS hypocrytes and scum. nothing more nothing less.
