Not that I've seen, but then again, the only boards that we've both posted on (to my knowledge anyway) have usually been fairly level-headed places with a minimum of stupidity.
But I do think Sek is probably right, I doubt it'll happen beyond the Wade superfans at the Torch boards, but it'll happen. That's the fun in the interweb, people take criticisim too personally and get carried away. You've experienced it yourself a bit, when dealing with Alvarez over Angle/Michaels. It's all over the place, if you criticise TNA then you're a blind WWE mark, if you criticise ROH then you 'don't understand real wrestling.' Hell, I've been called a piece of shit and worse for saying that I'm able to watch, and enjoy, Benoit matches.
