No doubt. Chuckleheads are always laughing for no reason. There's no inconsistency at all in pointing out what one of the actual proponents of abolition had to say about the phony claim of the victorious republicans that they had fought a war for the nonsensical reasons you keep repeating.
It's comforting to you commies to repeat that Southerners have a "lost cause" we're pursuing. Our cause is the restoration of the constitutional republic founded by ratification of the USConstitution. You fervently hope our cause is lost. I don't think it is.
Thanks for demonstrating that you've missed the point entirely and made a fool of yourself in doing so.
For over a century your side of the debate has cast itself as the heir to abolitionism and based on that title you stake out a claim to some unnamed moral highground on slavery. You have nothing of the sort and instead come from a tradition of the yankee war machine, its unjustly waged war, its coerced obedience, and its political - as opposed to moral - motives.
Faced with an authentic abolitionist such as Spooner you are repulsed as undeniably the guy was a fringe extremist. But that was exactly what abolitionism embodied, and Spooner as one of it's leaders filled the role of a brilliant yet flamboyant crackpot.
Revisionist yankeeland stole the name of abolitionism as the root of its supposed moral claim to justify an immorally waged war. Only one problem - the real abolitionists were still there and the crackpots pitched a fit when their fringe movement was usurped by political power grabbers to justify their agenda and behavior. That's why Spooner was so mad, and that is why his commentary is so telling - it exposes as a fraud the whole of your side's claim to abolitionism and, by popularly promoted albeit flawed inference, morally-grounded anti-slavery activism.
And as a side note, most political historians tend to include Spooner as a libertarian or anarcho-libertarian philosopher. He's still a fringer, but he's not the same as a leftist anarchist ala the marxian communalism you are probably referencing.
