You invalidate her experience by saying its just a phase, just a trend. What makes you think that?
The way I explained it to him is that it seems like he could be 'trying it on for size' to see if trying to resemble a female is something that fits comfortably with him but that he can't actually be a woman. So what need is it that is being met by calling himself a woman.
He seems very confused about specifics.
For example, I asked how does presenting in a feminine way as a male differ from presenting as an actual female? He couldn't answer this. I asked if it was society's intolerance of feminine men that made it easier for him to say he is female. He couldn't really answer that either other than to say he just wants to be seen as female so if he tells people he's female, they will go along with it and treat him as if he is. I asked how they would treat him differently and he just says 'by seeing me as female'. I said that people won't see him as female, they will register him as a transwoman. The same as, without judgement, we visually acknowledge someone's ethnicity, height, weight, etc. He then said he didn't need others to validate him which confused me.
We talked more about this today and he said that when he started reading more about transgenderism about a year ago he thought he would like to present differently to the world. He already had transitioning friends so feels comfortable with the whole concept and I honestly think he just wanted to join in and have a go for himself. To experiment. The things that he is doing/wanting to do are all superficial. He doesn't want to undertake hormone medication and he doesn't want surgery.
Furthermore, he said that when he first changed his name and pronouns it felt wrong to him. It felt like he was lying and asking his friends to lie. Now he has got used to it he says it feels normal.
I asked him what identity he is using on his job applications and he said he is using his old name and male pronouns for continuity. So at the moment he is actually 'deadnaming' himself. Which further confuses me.
This is why I think it could be a phase in line with the current trends.
Also, he has very little understanding of the impact on women. One thing we did discuss further today is self ID. I explained why I am against self ID and why it's so hard for me to go against that for him. I told him that he is more important than the rest of the world to me but does he expect me to drop all my principles because of that.
Very briefly (sorry don't want to bore everyone) we talked about single sex spaces and how this problem could be easily overcome with third spaces if the TRAs put their money and influence behind it and that women would fully support it too. He said that would still exclude transwomen from women's spaces and I said so what? - they would have the services, provision and protections they need, why do they have to prevent women from having the single sex spaces that they both need and are entitled to in law. He did agree once he thought about it.
We are still coming at this from opposing sides and have a long way to go. Sometimes all I see is a little lost boy, a young man who cut himself trying to shave his chest and I want to do whatever it takes to help and protect him. And then I see a young, inexperienced male challenging a mature female and I can't just give him what he wants because I'm not convinced it's what he needs and it would cause immense distress to me too.
Still struggling with this but really thankful to be able to articulate my thoughts here.
