I'm disappointed that you keep posting this stuff after it has been confuted.
It wasn't a "rebellion": it is ontologically impossible to "rebel" against something of which one is no longer a member.
Southerners always had the right, as did every State in the Union, to withdraw from the Union either singly or en bloc. If Alaska were tomorrow designated the National Trash Dump and Parking Lot, I'd expect them to withdraw from the Union, too, and for good cause.
Southern States exercised their rights as sovereign (we've established that), free Peoples to dissolve the ties between themselves and the Union, just as our ancestors dissolved their tie to the British Crown.
The level on which the Southern States acted was as Peoples, as Sovereigns.......please get it through your held, N-S, that as among sovereigns, there is no Law!
Among sovereigns, the only law is treaty law, and treaties are only as good as agreement among the principals makes them. Capiche?
MY, my, my, such big words. Using $10 words to support a 10 cent position buys you nothing.
Southerners, or any other state for that matter, have never had the right to unilaterally withdraw from the Union. Nowhere does the Constitution give them that right or the right to act unilaterally when the interests of another state may be affected. All you have given is your opionin that that right exists. I, along with the Supreme Court, disagree.
You can continue to parrot soverign states and states rights all you want. It does not change the fact that all you are spouting are your opinions on the existence of such rights. The states were soverign so long as their actions did not violate the provisions of the Constitution. They themselves agreed that laws made under the Constitution overruled laws made under their state Constitutions. And the Supreme Court has ruled that the articles of secession which they passed in 1861 violated the Constitution and were therefore illegal. That made secession illegal and their actions were acts of rebellion. Lincoln's duty to the Constitution required that he put it down by any means necessary.
So go ahead and troll the dictionary for more words. Make all the claims that you want. You are welcome to your opinions. I just think that they are wrong. Capiche?
