At what cost?
Not worth it in my opinion. A natural peaceful end would have caused no scarring.
That's an easy and cowardly assertion-- you weren't a slave. Your argument is void on its face because you can prove nothing about how long slavery would or would not last. As pointed out elsewhere on this thread, slavery thrives in China, Africa, and North Korea.
The Southern states were denying blacks' constitutional rights within the borders of the United States. Surely you're not going to argue that black people should be denied their rights under the Constitution? Or will you assert that they shouldn't have been considered citizens in the first place?
The war crushed the South and its ability to wage war-- which is the purpose of war.
All of those things that you decry took place and were products of the South and Southern actions-- and they all took place in the South. The murder of Lincoln (by a Southerner) gave rise to segregation, the KKK, and reconstruction.
The South asked for and got its war (you conveniently neglect to mention that the war was underway before Lincoln set foot in the White House).
Your assertions that this would be a better country if we had allowed slavery to continue in some detached-but-righteous country ranks among the most offensive things I've ever read on FR or anywhere else for that matter.
I frankly think you're mentally ill.
You need to get out of the business of defending slavery and take your racism elsewhere. You smell like a DU troll.
