See, now here you're just out and out lying. I usually have more respect for you, even if I don't agree with your positions or interpretations. Nothing Lincoln ever said can be remotely construed as "pro-slavery." What he did offer the south was an amendment forbidding the federal government from outlawing the institution. And he'd already said many times that he didn't think he had the constitutional authority to outlaw it. That's why the Emancipation Proclamation didn't actually free the slaves. It took the 13th amendment to do that. There was, however, nothing in the proposed amendment that would have stopped the states from eliminating it on their own, as all of the northern states had already done.
You guys are good at miscontruing intentions. If the north didn't hang all the confederate leaders for treason, it's because they were anxious to repair the union and move on, not because the south was legally in the right. If Lincoln offered to prevent the federal government from outlawing slavery, it's because he was trying to save the union, not because he was somehow pro-slavery.
I do agree that Lincoln's sole aim was to repair the union and move on.
