I grew up in South Carolina, the first state to secede from the Union. In our compulsory SC history classes, I remember quite distinctly feeling a sense of pride over this as kid. "We were the first! Yay!"
To be fair, the Civil War was about a lot more than slavery. That was beaten into my head back in AP History. But I've noticed on film's official discussion boards the trend of stating "the North was racist, too!" Duh. Abraham Lincoln was no friend of blacks, the Irish draft riots lynched black people in New York City to protest the war, and the North was segregated. But having actual laws, ala Jim Crow, is worse. Sure, the United States still has problems when it comes to women's rights. But compare us to places in the world where the laws of society are completely arrayed against women. "But at least Saudi Arabia is open about their misogyny!" Feh.
