The guidelines really should stipulate explicitly what constitutes trash-talking. I have always taken trash-talking to mean blatant insults directed at a team or its fans, taunting and boasting after a win, put-downs after a loss, personal attacks, and other obvious forms of trolling. I am not sure how or where the definition of trash-talking expanded into a straightjacket on how non-Bomber fans should act, how frequently they should post, or any other item of conduct that is not under the jurisdiction of anyone but the individual in question. Without any disrespect intended, only I decide whose opinions I should pay attention to, and whether or not they factor into my own thoughts and posts. Nowhere in the guidelines is it stated that fans 'visiting' a team subforum should 'pay attention' to the opinions of that team's fans, or limit the frequency of their posts.
Frankly, this issue is making it clear to me that the forum guidelines for conduct need revision and expansion for clarity.
