Respect is indeed a two way street. You have to give it, to receive it. Not everyone is able to formulate opinions in a manner which qualifies as mature, polite, and by first showing what is positive about the event or topic on discussion. All to often it is a case of the one who is raising the complaint, thinking as though they are deserving of some sort of reward or owed something simply for choosing this server to RP in. They think with blinders on, only able to see the prize ahead of them which they feel they were denied wrongly. This is not always the case, even when it appears to be. Many players are quite possibly labeled as emo or a whiner simply because of such situations.
All it takes is taking a few steps back and looking at things from both points of view, open eyes, open minds, and understanding that these DM's who take so much of their time to provide for the player base, have feelings. They serve selflessly, giving players so much of their time, creativity, assistance, and more. For what in return? We are all human. We all make mistakes. We all need feedback that is constructive even if negative. The best experience example I can give, was after a session I actually enjoyed greatly, I got a short tell basically saying good RP. I would have been just as thrilled to have gotten one saying good RP with suggestions on how to improve. Feedback does not need to be long and detailed, it just needs to exist and not be censored.
When it comes to negative experiences, don't go to the forums to complain or flame the other person. That is the reason we have the CC members. Send one a PM explaining how you feel about it, why you feel it was negative. Don't then bash the other player or DM in tells. If something was wrong, it will be handled. Feedback is important when someone has been slighted, even if just to let that one who felt slighted know they were heard, the issue is being discussed, and handled. Even if all that is done is counseling the offender, ensure something is actually done. This ensures that the one who felt slighted, no matter the perceived compared to the actual degree of slight, is comforted in the knowledge that the incident is being or was handled.
That said, even DM's make mistakes and censor even the best attempts at feedback. Censorship is wrong, no matter how you look at it. Everyone is entitled to their opinion, and has the right to express it. Just because it does not agree with how one DM feels on the matter, does not then give that DM the right to censor. As for Heretic's comment that he will punch back, good. You should feel able to stand up for yourself, defend your ideas or opinions. I'm not saying let's all post inflammatory posts, but this to is a two way road. Unless there is rude insulting and inappropriate language, there's no reason for censorship.
Kudos to the DM's who endure the bashing and continue to provide immersion, horror, macabre, fear, and so forth to this grand setting I've come to enjoy so much. Kudos to the players who already understand the points in this thread and maybe even my long rant, and kudos to those who learn something by reading this thread. Let's be patient with those who don't fit our idea of what is "right", and lead by example. Everyone starts out somewhere, and travels a long road which we all share at some point.
