I doubt many of the South who fought were fooled into fighting simply b/c they embraced the abstract states' rights theory. They were fighting mostly b/c the Yanks were invading, period. And everyone knew states' rights was an issue simply b/c it was the only way that the South could ensure the continuation of the institution of slavery! Nobody thought States' Rights was different from preserving slavery. Most of South were not slave owners anyway, but they still fought to preserve the system b/c their entire economic system and the South's wealth was predicated on slavery. Nobody was moral then compared to today's standards - the South was more tolerant of Blacks than the North. In the old NW they tried to ban ALL Blacks from those states, even in mid 19th century, even free Blacks, simply b/c they didn't want Blacks of any kind in their states. The South obviously didn't have this problem with the presence of Blacks, free or slave. VA has about 200,000 free blacks, I think. So who was more moral? I dunno, but neither were moral according to today's standards. Heck, Lincoln wanted to ship them all to West Africa, which he said to Frederick Douglas's face in July of 1862, much to the dismay of Douglas. Finally, the middle and lower classes did most of the fighting not b/c they were duped but b/c there are always a lot more middle and lower class people in the first place to do the fighting. But still, if we focus on N vs S rich people, the percent of rich people in the S who fought was almost certainly much higher than in the N, b/c, as I've already said, the S had much more to lose, financially, and the N could easily afford to buy there way out of the draft.
