Be a man.
It is a simple imperative, repeated over and over to men, starting when we are small boys. The phrase usually is connected to one man’s demand that another man be “stronger”, which is traditionally understood as the ability to suppress emotional reactions and channel that energy into controlling situations and establishing dominance.
Be a man, then, typically translates as: Surrender your humanity.
To be a man, then, is a bad trade. When we become men — when we accept the idea that there is something called masculinity to which we should conform — we exchange those aspects of ourselves that make life worth living for an endless struggle for power that, in the end, is illusory and destructive not only to others but to ourselves.
