Why do we need rules for this? We MtF's have been using women's restrooms for years and never had any epidemic of issues. If someone causes a disturbance in a restroom, they only need an ID for identification and not the gender/sex one. If they are guilty of that disturbance they should be charged for that and not for using that restroom as a MtF whatever. We need inclusionary regulations and not exclusionary. If they write and pass a regulation, what happens if they say anyone with a penis uses a male room and with a vagina uses a female one? That is, they may pass a rule where one has to be post op to get in, or prove that they are post op if they cause a disturbance. So, a broader more inclusive regulation/law makes is more workable. "Presenting as female" should be good enough, because it has been working just fine until recently, and will work just fine from now on. Everybody compromises a little.
