I’m a fan of the Good Touch/Bad Touch gambit myself. With your daughter in the ladies room have the girl yell “Stranger Danger - BAD Touch!” then have management call the police.
Your little micro-aggressor will be taken away by CPS, since you obviously brainwashed her with outdated anti-LGBT bigotry and hatred.
Will this be shouted before, during or after a molestation?
Simply require the person to be dressed as the gender they are ‘identifying’ as that day. That will solve the problem.
Predators hide behind the mask of being normal productive citizens, its how they gain trust and access to targets. Making them dress as a transvestite to be allowed in the womens room would put a damper on random dudes camping in the ladies room for sure.
I am a fan of “whatever happens to a vulnerable customer happens to their CEO too”.
