There is nothing wrong with banter, if there is a basic respect behind the trash talk. I can talk smack with the best of them, have on various occasions but I don't go out of my way trying to make people feel like failures or fools for cheering for their team. That includes Green Bay and St. Louis fans, although it is hard trash talking those guys since neither the Bears nor the Cubs can beat their way out of a wet paper bag.
Fun banter is one thing, being deliberately insultful is another. It is even worse when someone is marked as a representative of the forum. Being a moderator isn't all that great, I have been a mod and administrator on message boards much larger than this one. There have been times I have wanted to just tell someone that they are an effing tool and to get their head out of their arse but to do that casts more of a negative light on the site and why they allow to be moderators than it does on the person that is throwing the insult.
I know this, if I was posting on a board about an event and someone that was officially associated with that board started calling me names or saying that people who like whatever I am posting about is stupid then I wouldn't post there again.
Joe Madden is more than likely coming to the Cubs. This should be big news on this site yet the Cubs message board section is something of a ghost town. Maybe someone should think about that. If a Colts Fan was a moderator and kept insulting Bears fans on the Bears Boards how long do you think it would be before people left en masse for another board. That is the important thing about message boards, there are always other ones out there that can take the traffic if you run your members off.
