Yes, it's nice to have this board, where people aren't rewarded for attacking each other.
I think it's par for the course to dish on the contestants, though. That's half the fun of these shows - saying things that we'd never want to say to their faces. They agreed to be on a television show, and I think it makes them fair game. Of course, if I knew Amy or Zack in real life I wouldn't have this signature, and I wouldn't make fun of Zack's comments about lawyering.
You have done that, too, though. The "LOSERS" comment earlier in this thread, even the stuff above about slithering snakes, or when you called Dave a "power-hungry dork." We all make fun of these people.
I hope it doesn't sound hypocritical for me, for instance, to laugh at Dave's ears, but be unhappy to see Alex do it to his face. That's the magic of television, it makes it okay to dish. I do hope people agree there's a difference between television and real life - even though reality shows blur that line.
