Yes, slavery was an issue, but the primary issue was State's Rights.
Hahahhahahahahahahaha, holy shit, is that really what they're selling suckers these days? While one of the issues *decided* by the war was the question of federalism, it was, at best, a transparent pretext at the beginning of the war. This war, as with most wars, was unsurprisingly almost exclusively about an attempt to protect the wealth of the elite class from other members of the same class. That's not so easy to sell to the poor fuckers forced to leave their families to starve, though, so the demonization of the other side takes whatever form is most convenient.
As wars go, the US Civil War is really exceptionally boring except as a study in how long it takes a basically decent man of conscience to reach the point where he's willing to put total sons of ******* like Grant and Sherman in charge to win.
