It was consciously radical, though by no means always politicised. Fanfic, by contrast, is almost invariably acquiescent. It is essentially conformist, bound by a striving for communal consensus within the framework of B7 appreciation. Punk had the consensus from the start, using it as a launching pad rather than perceiving it as an ideal goal. But unlike fandom, it diverged naturally rather than seeking to converge.
Enthusiasm counts at least as much as actual talent.
One ignorant git once asked me how I could wear a CND badge and an Anarchy badge on the same lapel. Fandom is dismissed and derogated by the public consciousness, punks were treated with outright hostility. The subversive attitude of punk should need no elaboration. This is subversive. The free and unsanctioned appropriation of media texts is also subversive.
