The "Spanking Nun"
As a former Catholic (now devout atheist) I am more than familiar with the image of the nun as sadistic disciplinarian. (Hell, I lived it.) But while the imagery is more than merely occasional (see more) I just don't get the appeal. (And I liked American Horror Story-Asylum).
Sister Mary Flagella in action.
If someone can explain the appeal to me.................here is your chance! Just post a comment and tell me what I'm missing.
