During most of human history male members of the tribe were expected to defend the group and die fighting as may be necessary against raiders and predatory beasts. They were all warriors, even as on a daily basis they labored as farmers, herdsmen, potters, smiths, etc. In our frontier days men dropped their plows, grabbed their rifles and ran to face the evil that had struck. Again, it was expected of them and they killed those who tried to harm their families and the group as a whole. Today we live in "protected" societies and the warrior obligation has been relegated to others. A mistake. I am armed and will do my duty. Shouldn't you?
