I think that apart from Linux specific peculiarities (cf. 'git'), I guess that part of this might be due to European/American differences. My personal impression is that overseas work environments tend to be rather non-confrontational, with even raised voices often being seen as a persona attack, instead of a temporary "airing of grievances". In places I've worked in Europe (Germany/Ireland), this often was treated as the same reaction you have when you hit your finger with a hammer -- meant as a stress relief, not as attacking someone's core values and competences. Anecdatal, sure, but I've heard people tell of similar experiences. And my US data points included blue collar workers in Jersey, not exactly the pinnacle of PC, I'd say.
