This is easily the best distillation both of what I believe and what the left side of the peanut gallery's beliefs sound like to me. And, unlike most "attempts to explain" the PR staff over on the left side come up with, I don't think it's nasty or personal. Dialogs have been a powerful way of exploring ideas for more than two thousand years, and this one's no different.
