And I’d love to know the difference between fighting to keep slaves and fighting to keep an economy built on slaves

I doubt that, but I'll play along.

First though, we should make a distinction. Most people are ignorant. If we are to leave people ignorant of history, yes the Northern fairy tale is better than the Southern one. At least then they're not ignorant and racist. But here I'm arguing against fairy tales AT ALL.

Nuance can be weaponized, yes. That's a poor argument for always striving against nuance and contextualizing things. I haven't seen any pro confederate racism in this thread at all. I think we are not in danger of that happening here, now, in this conversation specifically.

I think we can afford nuance in this space. We don't need to silence it for fear of it being weaponized by bigots. There's very few if any bigots here, and the pro-nuance camp here doesn't deserve to be accused of bigotry. Maaaaybe pedantry, at worst.

Back to my first point:

The difference is one of degree. The North faced a similar dilemma of pro-slavery racism vs abolitionism a hundred years prior, but without the economic or political implications. That was a pure "racism good" vs "racism bad" debate, and "racism bad" won. Not a complete victory, but enough to undo slavery and some of the worst dehumanizing aspects of racism.

If you could, today, abolish slavery and child labor without giving up your iphones and milk chocolate and cheap clothes, that's an easy battle to undertake, morally. But you can't extricate the economic implications. Removing yourself from consumerism is HARD. We have fought wars to protect our oil even though we know it's bad for the planet. No, we didn't all agree with it, but enough people put their immediate quality of life above concerns for the climate and for the well being of locals. These people, you and I included, are not all unrepentantly evil.

It's a tradeoff. It's a spectrum. It's not all yes or no, black or white, good or evil.

"I will fight a war to preserve my right to be evil" is not a thing that anyone has ever thought or done. "I will fight a war to maintain my standard of living" is a thing that happens all the time, even when that standard of living is based on evil.

In many cases, the evil that the standard of life is based on is SO EVIL, it must be stopped. That's why the North was right. I'm not making some sort of both sides bullshit argument here. The Confederacy was wrong, and should not have existed. The tradeoff between harm done and standard of living for those on top was too much, by far. It was a morally good thing that slavery was destroyed, despite the harm that came to Southern whites because of it.

But the reason for understanding all this is so we don't fall into the trap of dehumanizing the Confederacy. They're not cartoon villains. They had rational reasons for why they were willing to fight to preserve slavery.

"People who disagree with me are evil, full stop" is a dangerous place for one's mind to go, and I'll always try to combat it. With the understanding, like I mentioned above, that nuance can be weaponized, and when that happens (not before), we can take the gloves off, ignore nuance, and berate the bigots into submission. Then once the bigots are gone, we can go back to discussing nuanced and contextualized hostory.
