Okay, so I hate to be the one to step in as the emo-faggot-liberal here, but... do we really want this?
First, history tells us that warrior societies are, time and time again, liquidated, err, I mean, liberated, by merchant societies. Well shit. I'd much rather live in a warrior society than a merchant society, too. But I'm not about to ignore reality.
Second, do you protect your offspring from being murdered/enslaved by other males by... murdering/enslaving those other males? Sometimes. But most times, it makes more sense (both in an immediate sense, for stability, and in a cosmic sense, for evolution) to protect via social order.
I don't think that is neurotic-wimpy-liberal. A hyper violent dog-eat-dog non-culture won't ever produce great symphonies (and, almost paradoxically, won't even ever produce great warfare).
So don't get me wrong. This sounds awesome. But how would it be reintroduced to the larger culture without weakening said culture / without it itself becoming destructive?
