Again, it's not "you guys" or "us." All the same members of this community.
I'm sensing you may have experienced what you're describing first hand. I'm not in a position to say what is right or wrong, since I'm not a GM. But I'm going to trust the mods when it comes to enforcing the code of conduct here and in game.
Finally, "attacking" is a bit of a stretch in semantics for my taste. Perhaps "strongly worded disagreements" would be more appropriate? I mean nobody is getting punched in the face here. Nobody is flanking an enemy fighting position here. It's a video game forum. Again, that's my view.
