Why do all the other sci-fi/fantasy groups have a cool name that marks the difference between a regular fan and well.....us?

It's so unfair. Before ROTS, before I was a Star Wars blogger I called myself a Star Wars fan. I enjoyed the movies, but in a comparatively casual way. This was back when the most that could be said for me was that I liked Star Wars, but back then I couldn't tell a bantha from a mynock, or an AT-AT from an AT-ST, or a Hutt from an Ewok (okay, that last one I knew, but you get my point). In my way I loved the saga, and I was a Star Wars Fan..... but now that I love the saga, now that I think about it everyday, and have used it's metaphors to guide the choices I make in my life don't I deserve something more? Don't we all? Don't we deserve a title that immediately tells the world what we mean when we say we are fans of Star Wars? A name that communcates that special level of devotion found in a relatively select (albeit self selected) group?

One reason I can think for us not having a name is the variety of ways that people identify with the saga. We can't say we're "Jedi", there are far too many who'd prefer to be a "Sith", and the "Senators" just sounds too weird.
Maybe by not having a collective fan title we have a certain amount of intellectual freedom that would be lost if we all decided we should be part of the "Alliance"

What do you think? Any ideas? Or do you know something I don't know?
