Define "class".
Class, to me, is about 90% ol' fashioned good manners.
I was stunned by your answer on the NWA example; as though using that word would be bad in Compton, because you could get killed, with the implication being that it's just fine to use in a situation where there is no threat.
I understand that people give these words power by reacting to them with offense, but that doesn't change the fact that a great many people react to them with offense. Part of living in a society, and showing some class or manners or whatever you want to call it, is respecting that. If you don't want to respect that, fine, but don't expect praise for it, or for people to buy your BS allusions to Chaucer & Joyce.
Seriously, if you're this way in life, I don't know how you get through it. I'm glad most people in the realm of my existence have at least a basic enough respect for one another not to talk the way you do (which, quite obviously, is geared toward eliciting some sort of reaction; I'm no psychologist, but there is no doubt an issue there....)
