The purpose of preferred pronouns is to legitimize the idea that being a woman or a man is an identity rather than a material fact of existence. It's intended to validate the concept of males being included in the category of women.
So, when female-only spaces are made 'inclusive' by admitting such males (i.e. those who want to be women, or who say they are women) then they are no longer female-only spaces. Eventually, if this continues, they will have been effectively abolished.
Which human right does abolishing all female-only spaces come under? As that is the end goal of this movement that starts so seemingly innocently with preferred pronouns.
