You never read the Declarations of Secession have you?
Short answer to half of your misconceptions. There were thousands of abolitionist societies in the North. So my question to you is how many were there in the South?
By the way, don't waste anyone's time and telling me the South was getting rid of Slavery. Slavery ended at the point of a gun.
I missed your explanation of why the underground railroad was underground in the north. Maybe it will come in the next revision of history.
If a hero is made of someone who was responsible for the death of millions in Cambodia, it won't be making any new history.
