Your post seems to echo this by saying the South’s main thing was they wanted to be separate, even though that happened to include slavery, there were other reasons too.

If so let me restate/reclarify: The South mainly or exclusively because they wanted to defend and further slavery as an institution (not even own states themselves; that’s a charitable way of putting it). However, the North didn’t give a shit about the South owning slaves; they just didn’t want them to secede and why both sides came to blows. To the North the slavery thing was kinda bad but really not the point; what they wanted to do is (to oversimplify) keep the South in the Union. That’s what I was trying to say.
