And BTW: I am continually amazed how people like you call it "the war of Northern aggression" when it was the rebels who fired the first shot, and moved aggressively--and illegally--to take over Federal government posts and buildings.
You're living in a dream world, the romantic myth of the South that never was...
Take a look at a battle map. The north was clearly on the offensive while the south was clearly on the defensive--hence the name War of Northern Aggression.
You asked me to "prove" it wasn't about slavery. You've been on this forum a long time-- How much more evidence could one offer to you? If you can't understand that poor southern boys fought and died for their homes and families then nothing I say to you will ever convince you otherwise.
I'll try one last time though. In the museum at Shiloh, there are letters on display. One is from a southern boy describing his exchange with a yankee soldier. It was unaddressed at the time of his death so it was never sent. It basically says this:
Southern Boy: Why you tryin to kill me?
Northern boy: Free your slaves!
Southern Boy: I ain't got no slaves!
Northern boy: Why you tryin to kill me?
Southern boy: Cause you came down here to kill me!
Don't believe me? Take a trip to Shiloh, Tennessee and see for yourself. But that my knock down some of those blinders you wear, so I won't hold my breath.
Politicians exude a lot of BS, but it was poor uneducated boys who felt the need to stand up and defend their homes and property against northern soldiers who came as aggressors. There is always more than one causation to any war--quit broad brushing all southerners who fought in that war as a bunch of bigots. They weren't.
