Strangely enough, I only remember sighing because sometimes, there are some really worthless debates.
Same rules apply. Don't like the debates? Stay out of them. It's not that difficult to not open a thread.
Utoptia was sick of all of the annoying petty debate's of people arguing over something as stupid as weather a character is a slut or not. And the petty debate was in the thread of a manga that he like's. I'd be pretty pissed to if a bunch of people started to bitch, whine & argue over something so insignificant.
