Maybe another way to achieve the same would be to allow optional anonymous posting. (With 2 caveats) 1. There's a way to recognize the same user in a thread - maybe color, or some way to say "This is the same user that you just replied to". 2. admins etc can see who you really are. I think then you'd be able to truly let your comments win/die on their own.
