Ta-Nehisi does a cost-benefit analysis and doesn't find the Civil War tragic at all:
Six hundred thousand people died in the Civil War, a shocking figure which doesn't really capture the toll that this sort of violence took on the country at large. And yet when I think about the Civil War I don't feel sad at all. To be honest, I feel positively fucking giddy. … The Civil War is our revolution. It ended slavery, and birthed both modern America, and modern black America.
That can never be tragic to me.
