ALL humans have natural rights that exist outside of whatever system men put in place. Honestly, Im shocked that you fail to understand the concept of natural rights.
If the yankee coven acknowledged the "concept of natural rights", then they'd also have to acknowledge that the South was right and they'd rather live under the yoke of a dictatorial communist regime waving the Constitution while trampling on it than admit that.
I understand them very well. I understand the state of nature, the social contract, and the natural rights one surrenders to live in society, which is the opposite of the state of nature. Revolution overthrows the social contract and creates a new one in its place. Sometimes this happens peacefully. Usually not. And the existing order has no obligation to simply roll over.
I'm more Hobbesian than Rousseauian.
