@ Neuro, anarchy has no authority except for the individuals own wishes as far as I know.
Anarchist societies would agree to terms in which they agree such terms are unvoidable like peacefull coexistance, moral levels, area of influence and so on.
The whole society operates as individuals and not groups, where each individuals point of view is just as valid as anothers and unarguable and collectively, such views are generalised as "Thats how we do it" sort of thing.
