Vague to the point of meaningless statement. “Phenotype” is a very general term that could comprise a variety of characteristics that differ/ vary in individual bodies. Phenotype is the appearance of bodies based on the interaction of genes and the environment. Our chromosomes determine what is commonly understood (scientifically and colloquially to be “genetic sex”).
Female phenotype is not a "vague meaningless statement", it has a specific meaning in human biology as it does in other forms of biology. Sex phenotype has a specific meaning too, I just thought sex was implied when I said "Socially, we sex on phenotype".
Our chromosomes determine both our phenotype and our genetic sex, but someone who is not doing sex testing saying 'genetically male' about looking for a dating partner - they are discussing their sex phenotype, because that's how we socially sex each other. How do you think we understood male and female & human attraction before genes were known about?
That doesn’t mean those treatments are medically necessary, because someone has a “serious medical condition”. They are typically done for cosmetic/ social reasons.
No, treatment for the endocrine system isn't done for cosmetic/social reasons. I have treatments for my endocrine system, no one can physically tell the difference other than I have more energy and I'm not being hospitalized regularly. I would argue most things to do with the endocrine system are serious, but I can get why others would disagree.
You're thinking surgical treatment which is a different kettle of fish.
Guys you are all misunderstanding.
And you're misunderstanding that individuals don't always fit into social categories, especially not academic ones.
Some people say I'm trans entirely because I have gender dysphoria even though I do not identify that way.
Some people say I'm cis entirely because I don't identify as trans even though many of the things that are meant to be 'cis', like being comfortable with my sexed traits and never questioning my gender, are entirely false.
I am erased in either group. You're paper is unlikely to cover people like me, but it's not transphobic to recognize the trans/cis binary has limits like most social models to divide people and for those who feel erased by it to discuss other ways of doing this. That's why many people discuss gender diversity, but that's apparently derailing to you that there are other models of gender, some which have gained popularity as research tries to be more inclusive of those models.
