“Do you not comprehend the fact that 1820s era nullification issues were not even the same generation of men as 1860s secessionists?”
Yes, and?
“By 1860 President Jackson, Senator Calhoun and all those people were long dead, and secessionists were not seceding because of a Bank of the United States.”
Yes, and?
“They seceded in 1860 to protect their “peculiar institution” of slavery against threats represented by the first “Black Republican” President-elect, Abraham Lincoln”
Yes, and?
I do hope you have a point in it. Are you saying that ideas only live as long as the person who first said them?
No, but since you already agree with my main points of the post, I'll let it go with that... ;-)
One point is the 1820 issues had been resolved by 1860. They had new issues.
One issue in 1860 was slavery in the territories. The slave power wanted it. The Republicans didn’t. The Republicans were willing to pass legislation and offer amendments to prevent slavery in the territories. The slave power was willing to start a war to assure slavery in the territories.
