there is clearly some sort of a "genetic" (historical) connection between socialism and anarchism, and it seems that at least some socialist anarchists believe that theirs is the only legitimate form of anarchism.
i strongly disagree. individualist anarchists are at least one strain of the big @ that stand apart from (and somewhat contrary to) the socialist strains. i personally don't like the hyphenated labels to describe myself, but i an an anarchist with strong individualist (among others) tendencies.
anyone that says theirs is the one true way is immediately suspect, in my mind. chances are good they are just stuck in their dogma and condescension.
a. there are limits and limits.
b. there is no need for a coherent structural understanding of social reality to be marxist. (the fact that marxism has been engaged by the people on top should be an indication that it's not a way to break out of the current paradigm. it's "realistic" perspective, which is why some people find it compelling, is part of the problem. but i think you and i differ on what is most useful when rejecting current social realities.)
"a coherent structural understanding of social reality"
most days i just hope to have a somewhat coherent understanding of the people i interact with....and very often, i don't....the possibilities for how i relate to/with them seem unlimited (even when familiar) to me.
