I believe people arguing "politeness" are missing the point, though. What I most value is "dialectics" (not sure if that term is commonly used in English).
I. e. the willingness to entertain the best argument against your position in good faith. Two people who are excellent in doing so (and familiar to HN) would be Scott Alexander of slatestarcodex, and Matt Levine at Bloomberg.
(Someone rather bad at it, usually arguing against some caricature of what he imagines his opposition to be, and generally tending towards the "either unactionable, obvious, or wrong" end of the spectrum is, well, Paul Graham.)
