I've addressed this argument at least 100 times on this forum. I think I addressed it earlier in this thread. The state official declarations of secession prominently mention slavery because slavery was the issue. It wasn't the principle. That is VERY important. We have to remember that slavery had not been outlawed, it wasn't illegal to own slaves, and the US's own Supreme Court had repeatedly defended the right to own slaves as property. So you are literally arguing the South declared secession over something that did not yet exist.
Yes, slavery was the prominent issue at hand, but it was NOT the principle on which secession resided. That was Federalism! Whether the US Federal government had authority under the Constitution to take the property (or in this case, render it worthless) of state citizens. MANY people (then and now) believe such issues are a STATE matter and the Constitution clearly states it as such.
Congress had 89 years and countless opportunities to condemn slavery and outlaw it. The SCOTUS also had ample opportunities to condemn slavery and render it unconstitutional. These things did not happen in America. That's NOT the fault of the South or Southerners. Are they complicit? Do they share a part of the burden? Of course! But to attempt to revise history so as to lay the entire blame at their feet is deplorable and dishonest. Furthermore, I believe it is done in order to scapegoat the South and absolve the North from any and all culpability. This is bigotry at it's finest.
More importantly-- Me, speaking this TRUTH is not an endorsement of slavery or even the idea of Confederacy. It's simply an acknowledgment of the truth, whether we like to hear it or not. We get nowhere by rejecting the truth and adopting an idiotic notion that doesn't comport with reality. You cannot absolve the North of the guilt for upholding slavery for 89 years by scapegoating the South. You cannot turn the Union into a bunch of Civil Rights Warriors who were fighting for equality against a racist South. That's a false picture of reality and I can't allow that to go unchallenged.
Actually it was the principal. You can read the articles of secession. It was that the abolitionist movement had gotten to the white house. That the federal government was no longer enforcing the Fugitive Slave Act. That the Government had passed law that new states could not have slavery in them. That the Federal Government outlawed the slave trade. Bit by bit they felt the noose slipping around them.
There's two things that show up in every state's Article of Secession. Lincoln being elected (and his abolitionist leanings), and Slavery.
You are right. Slavery was legal, but for how long. They seceded to form a nation that ensured the future of slavery in a Federal government they felt was about to drop the hammer on it. That's what they wrote about. To say "slavery was legal, all is fine" you need to get a really big fire going because you've got a lot of historical writings by those that seceded to burn to make that case.
To attempt to revise that, to take those black markers and cross out all the proof right there in their state congress meeting minutes, articles of secession and speeches about their cause is wrong.
To say it was federalism, when you had people like Joseph E Brown, governor of Georgia who truly felt he was leaving to join a new less Federally dominated Government and end up opposing Jefferson Davis later in the war because the Confederacy was every bit as Federally dominated just doesn't ring true with those that actually lived it.
When we try to say the truth is the principal was something other than slavery, and in their own articles of secession the states said "Our position is thoroughly identified with the institution of slavery" that's a lie
When the Vice President of the Country kicks it off with a speech saying "Our new government is founded upon exactly the opposite ideas; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science." saying it's something else requires you to revise history.
SO you are right. We get nowhere when we reject the truth.
