yes and no, i'd say.
there are multiple and conflicting tendencies in u.s. culture, including both an excess of personal responsibility (i am the master of my fate), and an excess of social responsibility (i can do nothing without masses of people).
--i'm short cutting, obviously; the point is that there are two strong tendencies that seem to directly oppose each other. yet they operate at the same time in the same person (all of us) just fine, cause folks're flexible like that.--
and both tendencies, i'd say, have something important in them. we are not atomized individuals, neither are we social drones.
so people can take *any* theory that falls between those poles and make it simplistic.
i wouldn't say individual anarchism is unique in any way, along those lines.
