Why did Nicola Sturgeon's policy for the few encompass the many?

I've just had a brief look at Nicola Sturgeon's comments on the Supreme Court ruling.  I think the timing is unfortunate, given how it distracts from the Programme for Government, and I also think there's a fundamental contradiction in what she's saying.  She's arguing that trans people constitute a tiny percentage of the population and that their lives are in danger of being made unliveable by the ruling.  In other words, the harm done to a tiny minority is wildly disproportionate given that any benefits to biological women must be very small due to the trivial numbers involved.  

But to make that argument stick, you would need to have a system that ensures the numbers of biologically male individuals who can access female spaces are genuinely small and that the reasons for them being able to do so are sound.  You would in fact need to have an extremely strong system of medical gatekeeping to weed out those who are not trans but are simply "at it", to use Humza Yousaf's famous words.

Instead, Ms Sturgeon tried to do the total opposite and introduce a system of self-ID, which means you would have no way of limiting the numbers or to ensure the people involved are 'really' trans.  If, as Ms Sturgeon claims, the threat to women comes from men and not from trans women, it's incomprehensible that she wanted a system that didn't limit male access to female spaces to just trans women, but instead opened up access to all biological men upon demand.  

It didn't make any sense when she was doing it, and it doesn't make any sense now.

I've never understood the overlap that seems to exist, at least in some quarters, between gender critical views and apologism for Israel's war crimes, but people who do this sort of thing should at least be aware of how needlessly they're alienating young people in particular. pic.twitter.com/XP5bYQJY8H

A woman is either of the following:

1) An adult female

2) The nation state of Israel: a true wonder of a woman. She knows her own mind. She has the right to defend herself. She’s fire wrapped in calm, danger in grace. She dreams deeply, and dares you to do the same.
