OK so do you want to state now how you feel about the south having slavery and the fact that they were willing to break up your nation just so that they could continue to do so.
Try and do it this time without distractions like 'well they treated the slaves well' or 'but, but, black people had slaves as well'.
How about we be totally honest regarding this then? Slavery in what eventually became the United States started while it was part of England and legally established under
English law. The reason it flourished in the south and died out in the north was due to climate and geography, not because of any grand moral crusade regarding the evils of slavery. England itself was well settled at the time of the colonization of the Americas along with not having the climate and geography nor any crop to support any establishment of a large scale system of slavery there but there was slavery in Britain until it was officially abolished in 1833 (unless it was in territories controlled by the East India Company). Is it your belief that if a large chunk of the British economy in 1833 depended on slave labor that law would have been enacted?
Do you really think there was any way other than war to end it in the US? The most valuable property plantation owners "owned" was their slaves, not the land, not the crops. The elimination of the slave trade perversely made them even more valuable to plantation owners who for the most part were up to their ears in generational debt which financed the facade of the aristocratic lifestyle they led.
