There’s nothing wrong with the term itself, except that it’s out-of-date.
Transgender people need to be able to update their birth certificates with their chosen names and experienced gender because other people are so frequently jerks to transgender people solely on the basis of them being transgender.
I really don’t know what it’s like to be a different height, as I’ve been this height for decades, so it’s hard for me to compare. But here’s a few things I’ve noticed.
When someone transitions or tells you about their gender, here’s something important to remember: it isn’t about you.
The term I think you mean to use is “Medically Necessary”. Whether a medicine or procedure is medically necessary is a question best left to the patient and their doctors.
There probably isn’t a large difference in the numbers of (binary) trans women and trans men, but non-binary people likely outnumber either of the binary genders. The reason you probably think there is a significant difference in the numbers is because more attention tends to go to trans women.
A few weeks ago, I was having a conversation with a friend and she said something which has stuck with me ever since: "Be kind to your unhealthy self, as you are kind to your healthy self." I was gobsmacked.
As a trans woman, I might bring a different perspective to this question, as I’ve actually had the experience of being perceived and treated as a man, as well as being pressured to look and behave like one.
