People of both sexes need privacy in toilets. It's possible to overcome the difficulties but you aren't interested in solutions, just in giving biological males access to all women's single sex spaces and services. You offer no solutions whatsoever. If transactivists put as much energy in to building trans specific services as they do trying to gain access to women's spaces, we would have solved half the issues by now.
It's not 'exceptional circumstances' in the Equality Act. The term is 'a proportionate means of achieving a legitimate aim'. Excluding biological male from womens toilets and changing rooms is considered a proportionate means of achieving a legitimate aim (privacy, dignity, safety). Just as excluding biological women from men's single sex spaces is at certain times.
Nope, you haven't proved that assertion.
Stonewall have routinely tried to undermine the provisions of the Equality Act through their training schemes, and in fact their Index scheme rewards companies for doing so. Perhaps that's why an increasing number of institutions are withdrawing. Even one of its founders, Matthew Parrish, has called its stance 'extremist'.
Essex Uni followed their misleading advice (no paywall) and were taken to task.

That seems a bold assertion. Not all transwomen have hrt or surgery. Some have neither. Not sure anyone of us are in a position to assess whether every transwoman has the ability to rape someone, though of course serious sexual assaults needn't include penetration.
And yet there are plenty of cases of transwomen being charged with rape and sexual assault.
Your hyperbole and emotive special pleading is a bit tiresome. You do not give a toss about women. There is literally no situation in which you would not prioritise the feelings of biological men over women. Not one. Not prisons, not sports, not changing rooms, not same sex hospital wards, not women asking for a female carer for intimate care, not rape counselling groups.
Is there any situation or service in which women should be able to exclude biological males? Any at all?
Let's be absolutely clear where you stand when a disabled woman says she only wants her intimate washing to be done by a biological woman, or a girl only wants to be in a rape counselling group with other biological girls and women. And don't bother replying if you're going to say 'I don't know anything about disabled people or rape counselling' like you do with women's sports - that's just your way of evading having to admit that sometimes single sex spaces and services are a necessity.
