But, the start of the Civil War started over a number of states rights issues going back to the origins of the nation. To boil it down to just slavery does not do justice to the issues of the day nor honor our national heroes such as Fredrick Douglas and Abraham Lincoln that lived by moral principle and honor.
IMO, the fact that the southern states decided to secede before Lincoln was even inaugaurated and the new Congress went into session with Lincoln as President means that no final decisions were ever made on any of those other issues.
It is not as if certain laws passed on all of those issues and then they decided to secede, they left because the Party founded by the Abolitionists won the election so decisively in the Northern states.
