DC fandom is delightfully mature. Despite all the many pairings we can come up (I'll talk slash for the moment as it's what I usually read and write, but there will be a gen observation to come), such as Bruce/Dick, Dick/Roy, Bruce/Clark, and an infinite amount of others, there are very few 'wars' (My pairing is better than *your* pairing!) and stuff that has happened in other fandoms. If people don't care for a particular pairing, the world doesn't come to an end. They just move on. The old Star Trek concept of IDIC (Infinite Diversity in Infinite Combinations) actually seems to *work* in DC fandom! People enjoy the pairings they like, may sample new ones, but no one is saying they *have* to like so-and-so. And even if you say your pairing is the OTP, it's done with pride, not arrogance. *You* believe it's the OTP, but you are perfectly OK with others having their OTPs, too. People seem pretty courteous in DC LJ-Land, or at least the communities I've joined. It's refreshing! All you fans should give yourselves a well-deserved pat on the back! :)
And that includes the fact that people co-exist between the gen and slash communities. I'm sure there has been some friction at some time, but believe me when I say I've seen friction between genners and slashers that can get pretty heated! DC seems (at least to my knowledge) to avoid that. So happy days again! :)
Now I could be wrong about this and people might have their horror stories to tell, but I'm working from my own observations. I was warmly welcomed into DC online fandom and am very happy here. Keep up the good work, folks!
