I can't recommend Echidne's post Fuck Civility post enough. Really, we have to draw the line somewhere. Ripping babies from their mother's breast is a good place to start.
For some reason I've been thinking of Albert Speer. To the day he died, he claimed he had no notion of the holocaust. He was just a pencil pusher tasked with getting stuff from here to there. Why stuff needed to be moved was not in his job description so he never asked?
