Last semester, a student in the masculinity course I teach showed a video clip she had found online of a toddler getting what appeared to be his first vaccinations. Off camera, we hear his fatherâs voice. âIâll hold your hand, O.K.?â Then, as his son becomes increasingly agitated: âDonât cry!â¦ Aw, big boy! High five, high five! Say youâre a man: âIâm a man!âââ The video ends with the whimpering toddler screwing up his face in anger and pounding his chest. âIâm a man!â he barks through tears and gritted teeth.
