People seem to be mistaken about why most teams accept certain standards. It's not about artificial politeness, it's about trying to get the best out of the team. Not shouting people down is good because it means that people who are more reserved but who have valuable things to add get their say. Not calling people stupid is good because generally people working on a project such as this aren't stupid and you're missing a chance to find out what really went wrong (misunderstanding, miscommunication or whatever). Even if what they have said IS stupid, not abusing people for mistakes is good because abuse is a sub-optimal way of teaching. Yes modern organisations have taken much of this too far and ended up as insincere, inefficient behemoths, but some of the standards within the community seems to be throwing the baby out with the bath water and taking almost gleeful pride in doing so.
