Nuns are violent cows that would use blunt objects, but strippers would scratch and bite - and probably move faster. Nuns are used to bullying children and only work over people smaller and defenceless.
Strippers have no morals, no qualms, and after faking soft femininity for paying punters, would gladly tear into a repressed old sow wearing a penguins burqah.
Strippers, for me.
