Fact is that all of us "selfID" when we use the toilet (or have you ever been asked to show ID or genitals?) and that is legal, according to the EA2010, no GRC needed. Do we want toilet policing like proposed in the US? An armed guard?
Firstly, there is a very obvious reason why your lot always focus on toilets - because it's low hanging fruit and, as you say, isn't actually policed in any official way. We generally rely on social custom.
But what about prisons, DV shelters or hospital wards? What is your view on that.
My mother in law was only saying the other day about how she is worried about males being on her female ward (she is ill at the moment and in hospital a lot) and she is only vaguely aware of this issue. Would you listen to her concerns, or would you hurl ageist and misogynistic insults in her direction?
Secondly, no toilets are not officially policed as we have established. However there are social conventions in place, both conscious and unconscious, which mean that generally, its fairly easy to keep blokes out of the women's loos. In a culture of self id, where everyone (including men who want to commit crimes against women) knows that any male can legally identify as a female with no gatekeeping whatsoever, that you don't have to produce a GRC to get into a toilet anyway, and that it is incredibly transphobic to make judgements or assumptions about someone's sacred gender identity, its a lot more difficult to keep males, including predatory ones, out of women's toilets and changing rooms.
And no, I'm not really interested in the 'well ur gonna get raped anyway, because men will always find a way, so we might as well remove the safeguards that are in place and allow anyone in to toilets and changing rooms and if you don't like it then you are a bigot who shouldnt be looking' argument either, so don't even bother trotting that one out.
