The thing TRAs always get wrong when they equate keeping male people out of female spaces with segregation based on racism or sexism, is that black people didn't want white institutions and society opened up to them because they wanted to be white, and women didn't want male institutions and society opened up to women because they wanted to be male. Nor was it because they particularly wanted the company of white, or male people, either.
They wanted to be there because that's where the power was. Because that's where decisions that affected their lives were being made, without them.
That's why these analogies, even if you believe some level of TWAW, don't stack up. Because womanhood, and women's spaces, are not a seat of power. In excluding male people from female spaces male people are disadvantaged nothing other than loss of access to female people.
Yet again, it comes down to trans ideologists' misunderstanding of womanhood as being simply what they see on the surface.
To a genderist, if it looks the same, then it is the same. If it's not fair to have white-only spaces, or male-only institutions, then it's not fair for spaces or institutions or opportunities to be female only either.
The context behind these provisions , the journey to get there both in terms of our society's evolving place for women and the journey of female people from birth to womanhood within that society, is unseen and therefore not factored in at all.
