The end point from the way things are heading fast is:
Completely de-couple anything to do with female human biology from the words woman, girl female. Note, this is not happening around male biology and man, boy, men.
The words woman, girl, female are reframed as 'identities' that anyone can adopt (as per OP who not only says TWAW (definition, adult human female, now considered a 'dog whistle' at best and hate speech at worst)
Any reference to female ...??? biology to be referred to in a standalone way irrespective of the dehumanising inhumanity in referring to (group with no name any more) as ovulators, gestators, menstruators, cervix-havers etc etc even though this will mean a lack of clarity around women's reproductive health etc with the obvious results
All the things that women fought for and are seen as important for (group with no name) around the world - single sex toilets, prisons, hosp wards, changing, sports etc etc essentially done away with
No stats that are meaningful to describe the experiences, difficulties, oppression, etc etc of (group with no name)
So the 51 % of the population who have been subjected to oppression all over the world and as long as anyone can remember, the group that still has to fight and fight to get their voices heard, the group that are still have an awful lot of struggle even in supposedly 'developed' countries
Have no name to call themselves as a group, no way of organising as a group, and no statistics to back up their arguments.
Well that sounds just AWESOME.
