Just to repeat for newcomers to this thread, there are many different ways a female person will use a toilet that requires privacy away from male gaze. Even nice ones who ‘just want to pee’ or ones who feel vulnerable in the male single sex spaces.
Often, women without caring duties will not have had to do this but it is not uncommon for women to have a push chair stuck in the door because you cannot shut it and you, as a recent mother, may have flooding periods to deal with.
Or you might have a child or a parent in a wheelchair when there is no accessible toilet available or free.
Or you have your shirt off or your trousers / skirt off dealing with blood, food or milk.
Or you might be vomiting with morning sickness or virus or any reason.
Or you might be dealing with menstrual blood at the sink.
Or… you might be unable to be in a space with an unknown male person for any reason!
These are not uncommon scenarios. I encounter women with their shirts off or unbuttoned regularly.
No male who respects women and girl’s needs would even consider using the female single sex spaces. ‘Just when there is no option’ is a dishonest depiction of the truth. The truth is. ‘Yes! I WILL use your spaces and if you have an issue with it, deal with it’. That is blunt reality of the situation.
Therefore, it is only different from other male attitudes by how often not by final outcome.
