(While I know that "fandom" is a popular and rewarding interest among friends I deeply respect, I'm happy to be a fan without all the other baggage. The craziness certainly can't be equated with the fandom construct, but it does seem to be an ample breeding ground.)
I'm glad not to need to take a side. The pressure to always have an opinion about everything is a self-important distraction of our time and culture, a far lesser substitute for a truly examined life. It's popular to rail against apathy, but well-chosen apathy might simply be a sign of humility and prioritized living.
That said, while I know some reactions to child sexual abuse (one of the dominos in this LJ drama) may seem extreme, I find it a far better motivation for action—even mistaken action—than those who cling to indignance even once their concerns have been addressed (regardless of whether they got their way—that's probably the real issue, aside from the feelings of power and significance that some may not want to relenquish). Dealing with issues surrounding child sexual abuse has recently become a regular part of my life. I've seen the effects of the powerful temptation to not even call it what it is, much less really address its implications and consequences. Who wouldn't want to avoid it? But we can't. We mustn't. It's not just a matter of lust and casual missteps, easily righted through self-examination and conflict resolution. It's deep sickness and brokenness, working out in patterns of power, control, and the violence of imposing will and action on those least able to resist. That's the kind of thing that requires response, even when it's not perfect.
