I have to disagree and agree.
For the most part I think most of the posters on the off topic boards are just expressing their views and talking about current events. I myself have been involved in many great threads that talk about current events even politics.
However I do agree their are attention hogs out there. When someone creates a thread with the soul intent of creating a flame war. That is an attention hog threads like for example "Belief in God produces hell on earth" or other threads that say something like "All athiests are idiots, or all muslims are terrorists" or "You'd have to be insain to believe (Fill in which ever belief). These threads are shameful and total attention hogs, they want to stir up trouble by insulting other peoples beliefs.
So in the end I think on the off topic board their are some total BS threads thats only goal is to create a flame war or insight hatred, then theirs the decent threads that try to create debates or inform us on global situations.
