The problem with so many of these responses, is that they seem to have given no thought to the consequences of self ID. From the Quakers' response:
We see a parallel between the contentious objectors having to “prove” their deeply held beliefs, and trans people having to “prove” their gender identity.
We believe that when it comes to something that in essence can never be truly known or experienced by anyone other than that person, a certain amount of trust has to be given to individuals to know themselves.
Well, yes, fine, identify yourself any way you want. If we were talking about people being able to self-identify according to their 'gender identity', and that was kept totally separate from the category of sex, there would be no problem with this.
What they seem to have failed to understand is that this means that any man can self-identify as a woman, and demand access to all women's safe spaces as a result. Of course, an honest consultation would have spelt out that this is what was being proposed.
The Quakers' response, along with some other vaguely supportive responses, seem to be quite vague, with just yes, no, don't know ticked and not many comments. It indicates a lack of understanding of the issues.
