It is tedious to have to keep repeating it, but yet again:
*If male-bodied people are allowed in women's spaces then predatory males can access them, as there is no way to tell the difference.
* The reason that women's spaces exist at all is because even though most men are not predatory, some are, and if male bodied people are allowed in women's spaces then predatory males can access them, as there is no way to tell the difference.
* Transwomen are biologically male. The majority have male sex organs, and all of them have male bodies. Therefore, although the majority of transwomen are not predatory, some are, and if male-bodied people are allowed in women's spaces then predatory males can access them as there is no way to tell the difference.
Most men are not concerned by this, as they realise that whilst they are not predatory themselves, some men are, and as there is no way to tell the difference it makes sense to separate men and women in situations where women are vulnerable in the presence of predatory men.
It is not considered discriminatory or prejudiced, or hateful or exclusionary to ban men from the limited number of women's spaces that exist, and nor is it considered to be tarring all men with the same brush. If you can't see that, you are blind, or choosing to misinterpret what people are saying.
