I have moderated forums (mostly World War Two topic) for many many years, and even though Angelo and I might not see eye to eye on some of his responsibilities as a moderator, he was more than within the boundaries of his position to inform Pixel that the topic of 9/11 wasn't in the true context of the subject matter.
A Moderator is there to not only moderate the subject matter, but to also end threads which either conflict with the disclaimer, or are in direct violation of the forum's rules and guidelines. No two forums are exactly alike, and some moderators look to keep a more stringent hold on the threads within any relevant topic.
In the case of our latest guest and his 9/11 reaction, there wasn't any measure of interest or involvement whatsoever, so all Angelo was looking to do was to keep the subject within the topic in context.
Now if only I can get these Moderators to log on with a different handle when "opinion posing".....Ohhh what joy that would be!
