Horrifying.
Girls' bodies seen as something to forcibly award to a boy as some prize he is entitled to.
Their humiliation and distress, their bodily autonomy, all meaningless. How much more could those girls have had it demonstrated that they are worthless beside males? When did we in history last have authoritarian nuts devoid of empathy or sense force distressed women to take their clothes off in front of them?
Compare the distress of having a private changing room and not being granted access to undressed girls, to the distress of being forced to expose your body to a male. No one believes that boy is a girl. If they did, they wouldn't care what he wanted or how distressed he was. In his private changing room where he didn't have to expose himself to anybody or be used as their resource. And when you realise that, you have to realise, these adults were meeting their own needs in abusing these girls. Not the child they did it in the name of.
