Your suggestion is that we allow any male person in that has had surgery.
What is the difference between a male person who elects to have their penis and testicles removed based on their philosophical belief in their identity or a male person who has their penis and testicles removed due to injury or disease. And thinking further, what about male detransitioners? Why should one get access to single sex spaces for female people and the other doesn't?
You never did answer these questions. Maybe you will here on this thread.
And why should female people who would be distressed by male body cues in single sex spaces be harmed?
Just having their penis and testes removed doesn't mean that these male people change their bodies to have female body cues.
There is no evidence at all that any male person in the UK at any stage of transition has a lower risk of committing a sex or violent crime compared to the general UK male population. What you are arguing for will still allow female people to be harmed because it is statistically expected that the same % of those males your suggestion allows into female single sex spaces will harm the female people using the space.
If a person from the group you have been leveraging in your determination to allow male people access to female spaces - those male people who do not produce the testosterone their bodies produces - doesn't wish to use the male provision, then they can find a safe alternative. Likely if they are phenotypically female as they have not processed any testosterone that they produce, they will use the female toilets if they have always done.
There ARE only two sexes. That is a well established and provable scientific fact. It is not being 'dogmatic' to understand that there are only two sexes and that sometimes the sex your body is, is relevant.
'If we are going to say men are the predatory, dangerous sex, then how do we accommodate those who appear - on any level - as being female?'
Male people are the category of people who are committing sex and violence against female people at a significant rate. Just because a person 'appears' female is not any reason to include a male person in a female single sex space.
If there is a need for a campaign to make male single sex spaces safe for all male people, this needs to happen as a matter of priority.
The 'compromise' solution is one of third spaces. This solution has been suggested for decades now. Not removing single sex spaces but adding a mixed sex space.
Your continued 'whataboutery' leveraging people's medical conditions where they have a difference of sex development can be accommodated for under exceptions to the laws and policies. As they already are.
However, your leveraging of people with differences of sex development in the way that you have now on this thread is you making their situation directly comparable to a male person who has elected to surgically remove their penis and testes. Is that what you are intending to do?
