It always pays to look who benefits.
Remember though, that this group of male people have sold an argument to some women that the 'benefit' is that with them, the men, broadening the scope of female definition, that female people will be 'safer' and less judged. I mean, look at the bonkers argument that women will be less scrutinised in sport because male people like Khelif and Semenya will stop people judging women from being masculine.
I don't think it even twigs in any way that they are using male people as the reason that women won't be judged for looking male as if those male people have broadened the range of body cues found in female people. They seem to think that this is not offensive. They seem to genuinely believe that this is righteous and kind and intellectual.
It is like the well if everyone was just kind and accepted men as being female, then gender non-conforming female people will be safe from being asked if they are in the right fucking toilet.
Of course, the hyperbolic way they present it is that somehow there is whole groups of gender non-conforming female people being violently evicted from female toilets. When that is not happening.
Not only that, it is like somehow the decades of gender non-conforming female people being asked if they were in the correct toilet for them never even fucking happened. Somehow, these men think that before them, no female person was asked. It is so fucking ignorant, yet how often do we see these arguments. It is constant.
All that has happened is some men decided to push all the fear buttons that some women have and present themselves as if their acceptance as being female is the answer.
