I guess I don't think of these groups too often either. I get the feeling that 90 percent of furries don't even know about them or have never visited one of their sites... and newbies would probably never hear of them at all unless they were specifically told. They had their day in the sun, but now they're well past being relevant.
It strikes me that there's something totally backwards about these groups, too. I mean, I consider myself a furry, but I'm not particularly deep into the fandom; I just participate in the things I like, and I have the freedom to ignore the things I don't like. Groups like these, though, define themselves by their hatred for the furry fandom, so you have to be WAY more obsessed with the fandom itself in order to be part of them. It seems like they're the ones who are obsessed, but we're the ones who are having a lot more fun.
I mean, if they want to express opinions against the furry fandom, that's great, more power to them. I can respect freedom of speech. What I can't respect, though, is that they always end up being more about creating and milking drama than anything else.
