The south seceded because it felt that the institution of slavery was at stake. Free states were gaining ground in the congress. Lincoln carried the free states ... it was the end of power for slave states. They bolted immediately. That is the history. Deny it if you will. But those are the facts.
Fascinating. (why dodge the question?)
Was the "Civil War" about slavery, or was secession about slavery?
If the war was about slavery, why did the North continue to enslave their fellow man after those in the South were free?
The North had slaves before the South, and maintained them after. From where do you pretend to get the moral authority to criticise?
Canada freed their slaves before any of the "United States". Are the Canadians morally superior to the North?(after all they are more socialist)
