The difference between me and you is that I do think they belong here.
I like don't like VN's, I just ignore threads about them, but isolating them isn't what should be done to make /a/ a better place. I wish I could say the same thing about Touhou, honestly, but I like Touhou, so no one is going to fucking listen to me on that one.
We don't need heavy regulation. This is constricting the community by clamping down on the rules, which we don't need. The quality of the community is NOT how well the community follows the rules. If you'll just follow my through process for a moment, you'd see that animesuki, narutofan, and a myriad of other anime forums on the internet follow pretty much the same rules we do (Although again, we have added anger).
Kicking out sections of /a/ that are grey area was not the best thing to do. The problems could be easily solved with an ACTIVE moderator, not restricted rules. There is a difference. A moderator that generally ignores grey area content, and deletes stuff when it ABSOLUTELY NEEDS to be deleted would be ideal. Let the community to their own devices, and only step in when there's someone intentionally shitting up the place. That's what this place needed.
I rambled. I hope you can still follow what I said. I need to get some rest.
