This is the kind of dynamic I feel like we get on any kind of social or political discussion these days, to pick something that actually has entertainment value as a redeeming feature. I doubt anybody's been paying close enough attention to my posting habits in particular, but over the last year I've developed a habit of dropping out of conversations at the point when I realize nobody's actually interested in communicating. That goes for myself, as well - I stay in if I think I might still have something to say that somebody might listen to, and I admit that I sometimes fail on the first part of that. Every so often I'll take a step back and realize, "Shit, it doesn't matter if I'm right, I'm not actually saying anything worth reading."
I'm not trying to imply that half the forum is interested in good-faith discussion, by the way. If you think I'm saying "The forum's been infested by stupid people, here represented by Blackrazor", you're as much a part of the problem as anybody. All of these discussions I'm talking about boil down to "This is my preconceived notion, and you're an asshole for trying to prove me wrong, so I'll be an asshole to you" shouting down "This is my preconceived notion, and you're an asshole for not agreeing with me because of reasons X, Y, and Z, so I'll be an asshole to you". The community doesn't seem to have the critical mass of people who want to have a discussion that my nostalgia insists it once did, and it's had an awfully chilling effect on my ability to want to say anything.
At this point, I still value Bay12 for a few particular users (and boy do I hate how cliquish I feel about saying that), and for giving me a place to talk. It remains a helpful source for current events, although I can no longer count on any kind of useful analysis. When I post in one of the threads I'm bitching about in this very post, I at least have an opportunity to organize my own thoughts and explicitly reason out why I think the way I do. But despite the tremendous role this forum plays in my life, I can't in honesty say I feel like I'm part of its community any longer.
I'm hopeful that'll change back, but I don't really expect it.
