I mean, gods, how many billion women were traumatized by their mother? But it's not like we pass laws saying "no woman who looks like your mother is allowed in the locker room". It'd be absurd. "The person who assaulted me had brown hair, we're going to ban all brunettes."

If you can't get over the fact that some women's genitals are a penis, that's a you problem you need to work through with a therapist, not the women who happen to have a penis (who also are almost certainly going to do everything in their power not to openly flash their penis at other people anyways).
