We are all flawed. I don't mean fans, I mean everybody. A lot of us whose flaws differ from those of the majority find a sanctuary in fandoms, DS, Trek, others. Our flaws often take the form of socialization problems, so you find easily hurt people thrown together with the pit bulls who go after others to compensate for inner deficits. And there are all sorts of other kinds of fans, too. It's a wide spectrum, and you have to find some safe niche like this site, where there's a sort of buffer against the pit bulls.
I also think that while fans often adapt poorly to mainstream society, another way of looking at that is that non-fans tend to adapt to mainstream society far too well. We require something better than standard consumer culture, we need a life of the imagination. I'll take fandom flaws over other kinds of human flaws.
Anyway, you can't make the pit bulls change. We can hit them on the nose with a great big rolled up newspaper and say, shut the hell up, bad dog, bad dog.... so to speak, though.
I'd like to see a fandom documentary done with the above attitude, showing the whole spectrum in a mature, respectful way. What and who "we"are, as opposed to what and who "they" (non-fans, "mundanes") are, and why, and what it all means, is an issue waiting to be tackled well.
