Why nowhere in Star Trek we saw people devoted to being fans of the Vulcan culture, the Klingon culture or the Ferengi culture? Humans studying Surak's teachings? Humans dressing like Vulcans for fun, or wearing this? People parodying Vulcans, Klingons in holonovels? We saw Vulcans and Klingons parodied by the show – the holodeck Klingons in Voyager were more or less a parody of themselves – but nothing intended as such by its fictional author.
