Didn't kill enough confederates. Every officer needed to be hanged, and their kids either killed or adopted out to black families (the people who were gonna do the actual raising anyway, and in many cases blood relatives because of all the rape), their wives sterilized, etc. Fighting a war of racial identity and subjugation should have wages of racial extermination and subjugation; that identity needs to be ended. Nobody should ever be able to meaningfully identify as that ever again.

After this we need to do something like that for the fascists. The weird stochastic terror groups. Anyone who runs a social media platform or mainstream news entertainment. Even if you're not a communist or anarchist, the capitalist regime must be dismantled to punish them. As much the christian church. If they want something similar, I'm sure they can find a willing imam.

We've been in a civil war since the Confederacy, it just went cold for a while. We never actually defeated the treasonous slavers or even held them accountable.
