I'm truly sorry you feel this way about the site but I understand where your coming from. I personally quit a site because of the back-stabbing and the fact that the forums guidelines actually supported it. There are a lot of bully's and cowards that post something on-line they would never have the courage to say to ones face.
I sometimes find myself either re-writing a post I made (because it sounds worse than I intended it) or reconsidering how another poster meant something. There's a knee jerk reaction to take the written words of others as bad as we can and I have to question whether they rally meant something a certain way.
I'd like to see you stay and just block some of the bigger blowhards here - as I have done.
Cheers,
Scott
