Hats off to these women. The tact is torturous and it has to be spelled out so clearly.
YES there are people who want it to be fast, easy and cheap to change legal sex
YES there are people who want to easily change birth certificates to say what they would prefer them to say.
The ISSUE is that this massively increases the entry of male people into female only spaces, which does not work for all women
So give them out like sweets if you want
AND
add additional spaces while making clear that some provisions are reserved for the use of female people only and there is no mechanism by which a male person can use those reserved spaces.
That will be unacceptable to some male people. And that is tough, because it's not only them who matter in terms of inclusion and feelings.
