Yes. Of the People...All the people, in the free exercise of Democracy (Not just the half that lost. You do not shatter a country over the poor electoral results, te secessionists are like Sore Losermen, with their own armies FCOL), and even a cursory glance at the treasonous secessionist documents tells you, flat out, that it was simply "we dont like this so were taking our ball and going home..."
Like the DOI says, governments should not be changed ad hoc for transient causes....
There was no Long train of injuries and usurpations....the founding fathers spent more time cajoling, begging and pleading with england, than the south did whining about lincolns election.And Lincoln, two months into that term would hardly have had the opportunity to enjoin the same manner of desptism as King George had.
So, I would think that absent the Lincoln=King George axiom, the Founding Fathers would have seen it Abes way.
As history does.....
Man, you really are short on the Southern cause, aren't you.
The nation almost saw war in 1828 when the Tariff of Abominations was enacted. Then President Jackson made a bold statement that he'd have to back up with force had those tariffs not been drastically cut. It would only postpone the inevetable. It was the passing of the Morrill Tariffs shorlty after Lincoln's inauguration which sharply increased those duties, and his intent to enforce that tariff that sparked the War of Northern Agression. Whether out of fear on the North's part that an industrialized South, with slave labor would harm the Northern industries, or providing a monitary source to fund Northern economic expansion, or as punitive to slave-holding states as a means to end slavery, or maybe a sum of all combined is moot because the increased tariffs only after Lincoln took office sparked the conflict.
Time after time in the previous decades to 1860, Southern state represenatives, along with some of the Northern states made pleas in Congress to establish a more fair and equally just duty assessment - without any progress. So, there were from the second decade to the sixth of "cajoling, begging and pleading" with the government to equally tax. That's about the same time span of oppression from England the assembled colonies suffered. That's upon the same cause the American Patriots of the 18th century made their stand.
Again, to define "treason" best is dependant upon which side of liberty one stands.
Again you do not know history! This proves it. There was over 60 years of pulling apart between the North and the South prior to the War of Northern Aggression. Start with Congress shifting a disproportionate burden of the taxes from the American War for Independence onto the Southern shoulders in 1793. Why? Because the Northern States couldn't afford to pay their fair share ... they were too poor economically. By the way ... THIS COUNTRY WAS FOUNDED AS A REPUBLIC ... meaning that representatives of the People go to Congress to voice their constituents concerns. Those representatives are servants of the People. We were NOT founded as a Democracy because the Founders recognized that in Democracy you have what is called the "tyranny of the majority" ... hence they gave us the Electoral College, Bill of Rights and so forth.
Go back and study your history, come back and talk when you get better educated. Read the book I told you about (but keep an open mind if you decide to) ... you just might learn the other side of the story.
