I don't know why not, I've been perfectly clear. If any state or states goes to war agains the United States in order to further their separation, like they did in 1861, then I would willingly take up arms to defend my country. Period.
Do you really think the south was a credible threat militarily? It could not hope to conquer the North, and it never intended to.
Then they shouldn't have started a war they could not win, should they?
My understanding was a hope that the North would eventually tire and realize they were wrong and maybe Europe would inject themselves into the conflict. The fault lies in ever thinking that Yankees were capable of doing the right and moral thing. Might makes right? Not. The Illinois ButcherTM was putting down a rebellion in the North at the same time fighting a war in the South. He was a good butcher, don't get me wrong.
