That's really it in the end. Sure with sports people get hyper fixated on being part of the team. However really almost all hobbies/personal interests are just geeks geeking out over what they love. Hell a "sommelier" is just a wine geek who turned it into a job. Foodies are food geeks, etc. etc. It all boils down to what society deems a geek seemingly based on what level of expense, or "coolness" the geek is into. The more expensive, or elite, the geekdom the less it is seen as geeky and more as sophisticated. Thus not being a geeky interest.I've always said "everyone is a geek about something". The only difference is that fans of stuff like Marvel or Star Wars don't think their cosplay or collection have any influence on the outcome of things. No one goes to the theater saying "if I wear my lucky Jedi Robe Anakin won't turn to the Dark Side", or "if I bring my lucky Iron Man figure with me the Avengers will beat Thanos".
