So this question is aimed to those people. Specifically, assuming we actually can set aside the inherent racism in the establishment of the Confederacy (and I want to stress, this is actually ceding way more ground in the debate than I'm actually willing to do, because all the first-hand contemporary sources made it blatantly clear that the Confederacy was founded as an act of racism and an explicit endorsement of the right to own African-American human beings as property)...but setting aside the racism, what exactly are you "proud" of when you fly the Confederate flag to celebrate Southern pride?
Are you celebrating the treason? Because establishing the Confederacy was an act of treason against the United States government, and it certainly does seem like the same people who fly the Confederate flag as an act of "Southern pride" pair it with the American flag as an act of patriotism. Those don't seem particularly compatible.
Or is it the defeat? Because I mean, I hate to be the one to be the bearer of bad news here, but the South lost. The Confederacy was dissolved, the political aims of their movement (which again, let's not put too fine a point on it, was the continued legalization of a brutal and harsh system of slavery) failed, and their army was roundly and decisively defeated. This does not seem, to me, to be something to be proud of.
I guess I might just be a bit confused. To outsiders, the Confederate cause was one of racism, treason and failure. I keep hearing people say that the thing they're proud of isn't the racism. So is it the treason or the defeat that you're celebrating? Please let me know.
