Driven and seduced by the physical natures within, men are pigs. To our young men today life is a very dark, grim and hopeless situation. Forever conditioned for practicality, stoicism, crudity, selfishness and simple-mindedness, men aren't worthy of the title. From birth through grade school, boys are taught that passionate emotional considerations are for girls only. Aggression is the manner and means to establishing self.
Boys learn through mass media, as well as their immediate environments, the social stereotypes.
Men are strong and women are weak. By encouraging, through various forms of identity support, the lower level, instinctive, emotions, men are essentially animals. Driven by the intoxication of hormones, the rush of adrenaline, and more, men learn to perceive their world in terms of kinesthetic pleasures and pains. Boys begin to see themselves as the center of their own tiny little world that everyone else is trying to impose upon. Therefore, men are aggressive toward each other as they see the other males as potential threats to their own little territory.
