I too wrestled with the 'label' for years. Pretty much all the same years in fact, although my diagnosis happened three earlier. If we're a subculture, we're a honking enormous one. The more discourse we have on this basis, the more we accept our true control of the culture that would seem to rest above ours, in the non-existent hierarchy of cultures.
