How about if people who want to create safe spaces just create the safe spaces they want to create, and we try to respect their need instead of making sure they’ve covered every corner case an uninvolved third party can imagine?
I’m pretty sure that if there is a large enough community of people abused by mascots in a given locality, someone will create a safe space for those people. The presence of a “safe space for female rape survivors” doesn’t preclude someone who wants to from creating that, nor a safe space for male rape survivors.
