Just a question. Are debates restricted to two protagonists? What about debates where there is one protagonist and one antagonist? Consider an hypothetical debate, "God is necessary for morality": could not Smith argue in favour with Jones arguing against? Smith's introductory post would describe why God is necessary for morality, while Jones' would describe why he is not. Then Smith would rebut the material in Jones' introductory post, Jones would rebut Smith's... and on goes the debate.
Man is a rational animal who always loses his temper when
called upon to act in accordance with the dictates of reason.
