Constant: the emancipation of the slaves by a decree from a victorious Washington DC was still very right.

Yes, I agree, and this in spite of my belief that the Southern states should have been left alone to secede in peace. Forcing white Southerners back into the Union at bayonet-point and achieving power over them through conquest and occupation was a moral crime, but using that position of power, once achieved, to declare Southern slaves emancipated, is no crime; kidnappers and robbers have no right to go on kidnapping and robbing, so there’s no victim in that particular case. And it’s a very foolish form of libertarianism that would object on “federalist” grounds. I think, actually, that most libertarians would agree, in the case of emancipation, and that “federalist” objections to Roe v. Wade really have much more to do with ambivalence about abortion than they do with a consistent decentralism.

Constant: And similarly, we might say, Roe v. Wade was handed down by Washington DC, and thus Rad Geek was really twisting the facts with his summary of what happened, but it was still a great thing for Washington DC to do.

Well, my claim wasn’t that Roe specifically didn’t originate in D.C. Obviously it did. I was making a causal claim, to the effect that something other than the good graces of the Nine made it inevitable that either Roe, or some similarly sweeping victory, would eventually be won. So the facts that I cite as an explanation are those that I think best support the relevant counterfactuals. If the Nine hadn’t handed down a (mostly) pro-choice ruling in Roe, then (I would argue) the abortion law repeal movement would have won through a different proximate cause, such as state-level legislative repeal, and/or through a growing network for safe and affordable illegal abortions. On the other hand, if not for the repeal movement, I doubt that Roe ever would have been handed down. Hence the claim that the movement is a better explanation for the eventual repeal than the Supreme Court is.
