This is interesting, since over here the extremely very few anarchists there are are most likely "anarcho-communists" or anarcho-collectivists...I think they have to work a little bit on their contradictions, but hey, maybe they could say the same about voluntaryists, I don't know. In my opinion too it's possible for pretty much every form of true anarchism to co-exist, if we accept non-aggression and voluntary interactions (That can also be applied to collectivist forms of anarchy if one is free to leave it if he doesn't wish to partake in fully communal life anymore, for instance)
