Akphi, very simple. You want to be the adult? Ignore the postings you deem childish and steer the thread back to the topic.
There's simply too many of them. There is very little chance of having an adult conversation down here. The thing that sucks for me is I'm battling some serious degenerates and then on occasion a normal person comes in and doesn't understand why I'm speaking like I'm speaking to these guys. They are insane.
