GW, using your own logic, the Confederacy had the same relation to "the principle of self-government and right to secede" as Lincoln to the principle of abolitionism. In fact, Confederacy had even less to do with the noble justifications you present for them then Lincoln with his own, but acknowledging the first sentence would be a good start for you.
I'm more thinking "Long term future" than "Right away."
Regarding the slavery arguments, obviously that's true. The North also had slaves, which makes this entirely irrelevant.
This was about self-government, for white people. Black people didn't really factor into it on either side. Neither side really cared about the African-American. Prove to me that one side was really fighting for them, and I'll consider it. Otherwise, it was a white man's war throughout. And the Confederate position, of wanting to secede, is automatically more valid than the Union's desire to prevent them from doing so.
