I think you're fantasizing quite a lot here. 'Polite' has nothing to do with 'fear' of gunslingers. And 'common, middle class politeness' is just a behaviour along the same way as not farting, swearing scratching your balls. "you're just not allowed to talk about them because then it would acknowledge class" No, nobody is worried that you're going to bring up class. There are some PC taboos which if broken, will cause some people to be upset, but that's more or less social politics, not class. "west coast culture is a lot like being around revolutionary marxists who make a point of being rude to wait staff because they think civility is bourgeois oppression," I don't want to upset you but this is a ridiculous. I respect creative contemplation, but this is nowhere near reality.
