The pure (libertarian) socialists' ideological anticipations remain untainted by existing practice. They do not explain how the manifold functions of a revolutionary society would be organized, how external attack and internal sabotage would be thwarted, how bureaucracy would be avoided, scarce resources allocated, policy differences settled, priorities set, and production and distribution conducted. Instead, they offer vague statements about how the workers themselves will directly own and control the means of production and will arrive at their own solutions through creative struggle. No surprise then that the pure socialists support every revolution except the ones that succeed.

This is more of a comment on radlibs and baby anarchists, but it strikes me as appropriate here. It's very easy to idealistically criticize everything that isn't the way it should be. At some point, though, you have to address reality.

No answer to that one.
