You just keep insisting on setting up that straw man, don't you? By the way, how is slavery doing in those states today?
You don't want to talk about the five Union slave states that did not have the Union Army invade them to abolish slavery?
Why do you not want to talk about the five Union Slave states? Why it's as if it undermines your claim that the war was fought over slavery or something.
I just find it curious that if your theory is true, then why were the five Union slave states not also invaded? Didn't they have slavery too? Wouldn't they have been a lot easier to defeat with those much shorter supply lines?
