Yeah, I'm not saying the people who caused the secession were good people. There's a lot of evidence that they're not. But choosing to secede I would suggest is a fairly mature act.

If you're getting a raw deal politically then extracting yourself from said raw deal is probably a better option than starting a war to assert your dominance over those who disagree that your deal is a bad one.

I think the people in the South had dishonorable motivations for what I think were ultimately honorable acts. At least up until they attacked the North first.
