As I said to another commenter earlier:
You would have us believe the framers forgot what the founders did.
The Colonies were already at war with Britain for over a year when the Declaration of Independence was signed. If the signers had survived into the 1860s they would have urged Southerners to be prudent and not rashly plunge into conflict.
The Founders didn’t forget that the didn’t write secession into the Constitution. Madison was quite clear that the Constitution didn’t allow unilateral secession at will.
The Hartford Convention rejected calls for secession. I also hope that if New York ever felt dissatisfied with the union that they’d try to work things out in Congress, rather than declaring themselves independent and seizing or bombarding the Statue of Liberty.
Also, was the government really that corrupt or tyrannical in 1861? And if it was, wouldn’t the slaveowners who had controlled the government for so long bear a big share of the responsibility?
