I'm betting on leggings at this point.
To put it another way; if you really loved freedom, you wouldn’t be “granting” freedom to wear leggings in return for our own to call you a creep.
He’s granting them the “freedom” from shame, and in return they won’t shame him by calling him a creep. If he has to become a creep, he won’t change himself he’ll try to change others by calling them names too.
