Even the extreme anti-capitalist anarchist Bob Black (the furthest thing from a Rothbardian) isn't sold on the idea that left-anarchists oppose the state:
The trouble with anarchists is that they think they have agreed on what they all oppose -- the state -- whereas all they have agreed on is what to call it. You could make a good case that the greatest anarchists were nothing of the sort. Godwin wanted the state to wither away, but gradually, and not before the progress of enlightenment prepared people to do without it. Which seems to legitimate really existing statism and culminate in the banality that if things were different they would not be the same. Proudhon, who served in the French national legislature, in the end arrived at a theory of "federalism" which is nothing but the devolution of most state power on local governments. Kropotkin's free communes may not be nation-states but they sure sound like city-states. Certainly no historian would regard as anything but ludicrous Kropotkin's claim that medieval cities were anarchist.
If some of the greatest anarchists, upon inspection, appear to fall somewhat short of consistency on even the defining principle of anarchism itself -- the abolition of the state -- it is not too surprising if some of the lesser lights are likewise dim bulbs. The One Big Union of the syndicalists, who also uphold the duty to work, is one big state to everybody else, and totalitarian to boot. Some "anarcha"-feminists are book-burners. Dean Murray Bookchin espouses third-party politics and municipal statism, eerily parallel to the borderline fascist militia/Posse Comitatus movement which would abolish all government above the county level. And Bakunin's "invisible government" of anarchist militants is, at best, a poor choice of words, especially on the lips of a Freemason.
If Black can see the statism hiding behind the curtain, why can't Brainpolice and the other apologists for these ideologies?
