did the CSA negotiate with Lincoln to preserve the Union...but keep slavery?
No, the CSA attempted to send diplomats to Washington to negotiate a peaceful separation, but they were turned away. This was followed shortly by the Union Declaring War on the Confederate States. Or are you going to deny both of these facts as well.

Wrong again. We've already been down this road, but likely due to thread tardation syndrome, it seems you've made a U-turn somewhere.
I think our side is looking at this the wrong way. We are trying to look at the whole truth which makes each side look bad but quite possibly makes the north look a little worse. Maybe we should all just try to make history fit our ideology like the other side and then this thread can just close since we'll all "be right" no matter what.
Neither side in an argument can find the truth when both make an absolute claim on it.
