Are you talking about Jessica Yanniv? That's another story entirely. That case involves a sexual predator of young girls going to businesses that are owned by ethnic minorities for the purpose of causing a lawsuit that will settle for a cash payout in mediation. The motivation is greed and racism, not advancing trans rights.
That said, why do you keep expanding the topic to other areas with other concerns? A gym only allowing in women is very different than an esthetician. My point in initially responding is that different things require different judgements. Sometimes the differences between males and females matter, and sometimes they don't. Each issue should be judged individually. Biology does not matter when deciding which pronoun to use. Biology is paramount in segregating sports based on sex. Biology matters when waxing vaginas or penises. Biology doesn't matter in fully clothed areas of a business.
When transgender activists claim that biology never matters to any issue, I consider that an overreach. When anti-transgender activists claim that biology always matters to every issue, I consider that to be lazy thinking. A claim of the sort, "We should only use 'he' and 'she' to refer to biological sex because competitive sports should be segregated based on biological sex" is a non-sequitur. Pick one issue, not the monolithic "Transgenderism", and discuss that.
Compare it to racism. There may be something to claims of racial profiling in the criminal justice system. We shouldn't automatically discount that because some folks advocate for racial quotas in businesses and universities. They may be related through the monolithic "Racism" but that doesn't mean they're connected in a relevant way to compare them.
I am expanding the topic because pronouns are related to the basic topic about people self identifying their gender which includes transgender people. It is all part of the same ideology that there are no male and females and gender is only determined by subjective feelings. This is partly responsible for the conflicts and confusing we are seeing.
I am not referring to the Jessica Yanniv case in particular but in reading about it it does show that people can and will take advantage of the situation. But more telling it seems that despite this transgender being vexatious the courts seem to be empathizing with transgender rights in these situations. This has implications of forcing women into doing things they don't want to do because of anti-discrimination laws which have gone overboard. IMO it is still an example of the consequences of redefining women which will inevitably bring up situations like this. This example is just one of many similar genuine ones. For example
Local transgender student with penis sues school district to be allowed to change clothes openly in woman’s locker room
Anyway I don't really want to get into naming individual situations as examples of how males and females are different and rather talk about the overall implication of what redefining a women will have for women and men for that matter. The differences extend across a number of areas such as mentally, emotionally and socially. Biology is more than the physical features. Every cell in our body is either male or female so it affects people in many ways. Women's spaces, their privacy, every right, safety issue and any other advancement we have gained for women is at threat by redefining who a women is.
By accepting that a person can self-identify as a woman we are saying that there is no category for cis women socially, biologically and politically and this has consequences. For all the rights, aims and protections that society has stood up for and continues to recognize these will be diminished and in many cases completely eradicated if biological males can be women. There will be no special consideration of women because everything that a man can be and do will also be what a woman is.
It would cut all ways for women in that existing cis women would lose many rights and recognition's like for equal opportunity in work and promotion. If a biological male can be classed as a woman, then any ability they have as a male that out competes a woman will no longer be seen in terms of gender inequality but a fair and equal part of who a women is. This will be applied to all areas of women’s endeavor such as sports, journalism, business, finance, adventure, recreation and so on. Anywhere a male is shown to be more dominant and successful because they are a male when applied to women’s opportunities will be diminished and taken.
Any women’s space where a woman wants their privacy will also be diminished and taken such as toilets, change rooms, gyms, women’s groups, medical programs, support groups, women’s hostels, etc. Cis women will no longer be a category and have the same rights.But what I find telling is that it seems to be predominately men becoming women and women being affected and that people are very quiet when these situations are applied to women becoming men. What about when a women has to use an all male toilet, change room, hostel or jail. What happens when a young girl has to use an all male change room or toilet. Would people be as accepting of this situation as it exposes more clearly how men and women are different.
As an article in the conversation mentions
Why self-identification shouldn’t be the only thing that defines our gender
If you don’t think that women should be provided with these legal protections – women only spaces, or resources put aside just for women – then that is one thing. But if you do, then the category of “woman” as a matter of self-definition is self-defeating.
The logical conclusion of shifting our definitions of gender from objective characteristics to inherently subjective and personal ones is that the categories of “man” and “woman” effectively become meaningless. This is not a satisfactory outcome, especially for those who strongly feel that they identify as one particular gender. It is natural and understandable to feel empathy and concern for those who feel pain and distress at their socially recognized gender, and who wish to transition to live in the opposite role. But shifting our definition of what it means to be a woman so that it no longer has any grounding in the material or social reality of what it means to be a woman helps no one.
