In the same way if I need help I don't know who is a genuinely kind lady and who might take advantage of me (Women do go out and set traps for thie r murdering partner you know, it happens. Have you researched how Ian Watkins got access to all of the children he abused) Now the obvious response is BUT THATS NOT ALL WOMEN. No it isn't. It's a minority. It's also a minority of people who actively access showers to look at women (but this is a none argument as I've already said certainly where I'm from, most showers are perfectly visible from the pool and mixed). So what's the answer there? Separate pools for men women and trans?
Sorry but the statistics just do not back up what you are saying at all. 98% of sexual offences are perpetrated by males, that's huge.
Its a huge part of the reason that we have single sex facilities in certain situations. Single sex toilets, changing rooms, refuges, hospital wards. Its why even the nice men can't come into female spaces. No one has a problem with single sex spaces when men identify as men, so objectively, what actually changes when a man feels like a woman on the inside?
Further, women are always told to take steps, to curtail their behaviour to 'keep themselves safe'. Don't get too drunk, don't wear revealing clothing, don't walk down dark alleys at night alone, don't get in taxis alone, there are perverts and dangerous men everywhere etc. And everyone knows we are talking about protecting women from men in these situations.
But as soon as women make suggestions of things that will help to keep them safe, but may mean some males not getting do what they want, then all of a sudden we are paranoid, unkind, women do it too you know blah blah blah.
