That's exactly the way I like it, because it's honest. If I say something stupid, I want people to say it's stupid. If I say something intelligent, I want them to say it's intelligent. The concept that I would be dishonest or hold my tongue instead of saying exactly what I thought for fear of what the listener would think of me is little better than lying to their face. The world would be a healthier place if everyone was called out on their stupidity, every time, by everyone there.
Anonymity enables honesty. Rigid identities are for people who are afraid of what they might hear if there was nothing protecting them from the truth of other peoples' thoughts.
Do you think this comment is the most ignorant, idiotic thing you've read today? Then tell me so, without being influenced by who I am, or dissuaded by anything I might do or think in the future. I welcome your honest opinion, for I know it is based purely on what I have said.
