I think the following sentences are fact:
Some men commit crimes.
Violence against women is overwhelmingly committed by men.
This leads to the logical conclusion that a unisex space is more dangerous for women than a women only space.
Another fact:
Self ID is an opportunity for men (some of whom commit crimes) to commit a crime by abusing the process.
This means that Self ID will give some men (men using whatever definition you use, i.e. even if you exclude trans women from this definition) more access to women’s spaces.
This means (following logic above) Self ID increases risks to women.
Other facts that people may choose to add in don’t actually change this logic. So ‘some women do bad things’ or ‘not all men do bad things’ or even ‘trans women are women’ don’t alter the analysis above.
So surely the only argument should be ‘is the benefit to some people of Self ID worth the detriment to others’?
Have I gone wrong somewhere? Or if not, why are people so reluctant to name it on these terms?
