I'm sorry, but that's just a polemicist's chestnut. I've explained it to you, and if you want to insist on being a South-bashing neoliberal, I guess you're at liberty. But you won't go uncontradicted on this board.
I can go "contradicted" all you want and that still doesn't change the fact (not chestnut) that the war was all about slavery. All you neo Confeds can scream tariff all you want and there is no support for it.
