Has it faded? I can only claim detailed knowledge about the history of Scandinavian men's culture, but if that's any measure of what's going on in the "West", it's still here - it's just lost much of its prestige and visibility in the field of middle- and upper class public discourse. The honour-motivated crimes of foreigners are proof of their alienness, while the honour-motivated crimes of ethnic Scandinavians are dissolved into other categories - tragedy, mental illness, random incomprehensible violence, overindulgence, age, class, politics, plain old stupidity...
Culture is sort of like a palimpsest - unless the information and the entire substrate it existed on is utterly obliterated, it's always available to be resumed or resurrected as a strategy when it becomes useful again. We still do incredibly stupid vile shit, and egg others on, in the name of saving face, it's just that "his girlfriend told him to 'man up' when some jerk cut them off in line for the taxi home late on a Saturday night" does not appear with a checkbox next to it in police report forms, even though, as a reason to kill someone, it's as old as the Sagas.
While we're on the subject, how is James Bowman's "Honor: A History" regarded? I have a copy floating around but haven't gotten around to reading it yet; worth the time?
