Obviously, you have a major, major problem with historical truth, since even when you speak it, you turn it into a lie.
I have to admit, that takes some kind of "talent".
Now, I've explained the real truth to you over, and over again, and yet your wooden brain won't grasp it.
But I'm patient, will try yet again:
Contrary to "popular opinion", slavery was not so much America's "original sin" as it was a precondition for: 1) successful settlement & prosperity of Southern colonies, and 2) agreement for the 1787 constitution forming one United States, instead of two Dis-united States, one free, one slave.
Throughout the period from 1787 through 1860, slavery was fully understood by all to be acceptable in the South where it was legal.
No major politician, not Lincoln nor the Republican platform, even in 1860 advocated abolishing slavery in the South.
All agreed that slavery in the South was strictly a matter for Southerners to decide.
Of course, since the early 1800s, more and more Northerners, and even some Southerners, had come to oppose slavery, and were willing to vote for political parties which promised to contain & restrict slavery -- hence the demise of Whigs and rise of Republicans.
After the Confederacy provoked, started and declared war on the United States, while sending military aid to pro-Confederates in Union Missouri, then the Union began to consider military advantages to freeing "contraband" slaves under US Army control.
So, step-by-small-step, the Union Army issued orders, first protecting "contraband" slaves, then Lincoln's Emancipation Proclamation and finally, in 1863, proposals for a 13th Amendment to abolish slavery constitutionally.
Bottom line: slavery was a precondition for Southern states' economic success in the 1700s and a precondition for political Union in 1787, but in 1865 abolishing slavery became a precondition for reestablishing the Union.
So, tell us FRiend DiogenesLamp, what exactly is your problem with the truth?
"And apply it to the Union. You know the truth, you just can't speak it. Here, I'll do it for you. "If there was no rebellion, the Union had no problem with slavery here."
