Yes, they should have shot everyone. Especially the slaves who fought beside and in place of their owners. Men, women children, all of them. After all, they were criminals, right? Why, I'm sure you can point out numerous cases where these instigators were convicted of treason....
Surely you can. Can't you?
The Constitution doesn't recognize the right to secede...
And it prohibits secession...where, exactly?
Lemme guess. Public school student?
Oh? Didn't see that spelled out in Article I.10, nor in Article IV, nor anywhere else in the enumeration of requirements and limitations of a State.
In fact, if we undertake your assertion that the Southern States never left the Union, then according to IV.4 Lincoln is the biggest criminal and traitor in U.S. History for inflicting upon those States the 'domestic violence' the Constitution demands he protect them from. So that argument is a non-starter.
As for your other comical assertions, please refer to:
Amendment IX
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
Amendment X
The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.
Unless your argument is that these, along with other large tracts of the original document have been effectively dead letters since 1865? I'd agree with that, and the nation as it stand today is a direct result of the Constitution being an interpretive, 'living document' whose plain words mean not what they say, but whatever is convenient for the day. In a world of honorable governance, this can be an expediency that provides benefit. Of course, you'd also be living in a Bizarro alternate universe, since the one unchanging engine of history is corruptability and will to power.
The Framers designed the Constitution as they did, not to guarantee regular gatherings for tea and scones, but to prevent the success of the will to power. When their words no longer carry weight, the chains are loosed, and the men of power usurp the word of law. Which makes up different from every other pissant banana republic only in nomenclature.
Is this what you are in favor of?
Want to bump that up 135 years and try the first part again?
Damned few south of the Mason-Dixon line voted for Lincoln, but that is just one indicator of the division.
My ancestors took an oath to the Soverign State of Maryland after the Revolution. Under the Articles of Confederation, the several States remained Soverign. Under the Constitution they formed a Federation, (NOT a National Government, but a Federal Government). After the war of Northern Agression, the National Government bit started, to our detriment as much as our benefit.
As for the Constitution, that venerated relic probably has not even been read by 10% of those sworn to uphold it, or if so you could not tell from the bills they propose, the laws they pass, the executive orders, or rulings from the bench.
