I know it's hard but just because someone is mean to you doesn't mean you should act the same to them, I understand when someone is being rude to you you have a very strong impulse to be rude right back, but that only continues the viscous cycle and ends up making topics that started out with some sort of point into mindless attack threads. the recent example would be Fang's thread.
I believe a lot of the people here are at least 18+ ,now i could be wrong but, i think we can all be a little more mature when it comes to this. If you have a problem don't post it in that thread send them a PM and try to work it calmly, you could even invite a third neutral party to help things run smoothly.
