There are certain topics that I don't like to discuss anymore just because of the fact that they have been beaten to death. Sometimes it is easy to forget that there are new members that open these topics again and you can't really blame them, I know that I may have been annoying in the beginning myself. The problem is we should not shut down discussion as a whole, conflict is natural the problem is people going intro cursing rants against each other or the devs. I'm proud to not be part of that group and have never used profanity. There are still major problems that I and others may bring up from time to time and I see nothing wrong there, otherwise the forum would be dead.
Different people have different experiences that lead to different conclusions, maybe there is something to learn or maybe not.
I don't see any big problem honestly and most trolls have been taken care rightfully and professionally by the mods, some of them have actually been entertaining for 5 seconds or so.
