Look Non, I was in the process of long, point-by-point refutation of your last post but frankly, I can't put it any better than this gentleman. So please, as a matter of your own edification:

Ah Tommy and his tariff. I'' tell you, you're going to have to do a whole lot better than Tommy DiLusional. Let's start by asking this question. Tommy places great importance on the party platform, and says "the protectionist tariff was a key plank." Actually it was number 12 of 17, hardly a key plank, but regardless of that if the tariff was such a burning issue in the South then why does neither Democratic platform even mention it? Neither the Douglas faction OR the Breckenridge faction ran on a platform that mentions tariffs at all. Both platforms call for conquering Cuba and a transcontinental railroad. Both support slavery in the territories. But neither mentions tariffs, much less condemns them. Why is that, do you suppose? If tariffs were such a burden?
Why, if tariffs were such an anathema, did the confederate congress pass a protectionist tariff right off the bat, in May of 1861?
So if tariffs explain Lincoln's motivations then what explains the southern actions?
