The founders disagree with you. They articulate that our own legitimacy is built on this natural right to be free.
Secession is a legal process to withdraw from a union, a legal process that is nowhere in our constitution no matter what the southern rebels claimed.
We've already covered this. There was no need to put it into the Constitution because it was already very well covered in the Declaration. Again, it was only 11 years later, and they would not have forgotten they wrote this.
No, your wrong. I have already provided four quotes that clearly show the founding fathers called it a revolution or rebellion. If you can provide quotes from the founding fathers using the word secession to describe their revolt from England I would be very happy to look at them.
