I’ve got a lot of these.
Video gaming. As others have noted, there are a ton of idiots. Luckily, I have several friends who work for video game companies so they play professionally and avoid the rampant stupidity that seems common. I think a lot of the stupidity comes from small children have access to video games at a much younger age. My brother James, who is 12, loves World of Warcraft and is a member of a guild. He’s been playing since it first came out with all of his grade school friends.
Comic books. I have a small group of friends that I talk about comic books with, but I’ve gotten out of the scene in general. I used to be so involved that I worked in a comic book store to and went to conventions. Part of the reason why I left the convention was because how I was treated as a female fan. I would either be dismissed or ignored because “girls aren’t into comics” or fawned over to the point where it unnerved me. Now that comic books are more mainstream, I doubt that’s the case, but I’ve been out of it for so long and I have several local friends with whom I can argue "who would win"s so I have no desire to get back into the community.
Cosplay. Although I have friends who are widely respected and famous within the cosplay scene I can not stand it. I love making costumes, dressing up, and posing, but the cosplay scene is full of so much drama and craziness that I refuse to be associated with it. There are whole groups of people that make fun of other people’s costumes and pick on them for accuracy. People will identify with an anime character and will strive to be known as XX cosplayer by being the best at that type of cosplay.
Shooting. As others have said, I’m not a rabid NRA lover. I have a friend who only votes for whoever the NRA tells her to even though she’d be a complete liberal democrat otherwise.
Raves. I don’t do drugs, not even weed. I like the feel of being packed in a tent or under the stars in the desert while pounding your feet and shaking your soul to powerful music. I go with my friends, dance for hours, and then leave. None of us hang out with ravers outside of raves.
Gothic/Industrial music. While I enjoy dressing up in gothic clothes and hitting the club scene, it’s just something that we do every other week or so. I’m not the stereotypical fan with loads of black eyeliner, black nails, and black clothing writing angsty poetry while listening to NIN. In fact, I try to avoid angsty people.
Anime. I got out of this scene for the most part. I used to attend all the cons I could and now I go to 1 or 2 a year. I used to spend all my money on it (anime - crack is cheaper), talk about it constantly with fellow geeks, and even started up anime clubs. I studied Japanese so I could read my manga. Now, I only care about the porn aspect of it. I made the mistake of rooming with hardcore anime fans at the last con I went to and I was reminded why I got out of the cons. A lot of anime fans use cons as a means to hook up. There was a ton of alcohol and a ton of drunken sex. And then of course, drama and emo because everyone dates/fucks everyone in their group. I felt like I was in High School all over again. Although I really like my friend who was in charge of organizing that room, I’ll be sure to avoid staying with hardcore fans again.
I’m sure I’ll think of more later.
