No disagreement on that point. Since when did the south think other states didn't have rights? Unless you maybe are refering to the Fugitive Slave Act....that involves property rights. You know, the right to own property without having it stolen? But you guys apparently thought our rights were less, or something else. The South would not have tried to coerce Northern States by force, and you can bet on that.
In their acts on unilateral secession. They did so without a thought that the other states had rights and issues that were negatively impacted by the southern actions. The southern states seized federal property, repudiated their responsibility for the national debt, blocked access to the sea for markets along the Mississippi river. Didn't the rights of the Northern states matter? Or did they have any rights at all?
