I think you can refocus the modern aggressive threatening behaviour of young men into either a physical or psychological aspect of masculinity that celebrates being respected and admired for the safety projected by them. A ‘real man’ is someone who makes sure everyone is heard, everyone is safe, everyone can rely upon, and that no one can get away with shit around. They should be beacons of safety, strength of character, and patience. I believe our ancestors gained this by survival, team bonding through necessity and respect for the danger of nature. Humility needs to come back in a big way.
