As I said before, "born in the wrong body" is actually not quite accurate, but it's used to approximate an explanation for people who aren't familiar with ideas like gender roles. Gender isn't a biological concept, it's a sociological one. Gender identity is whether you identify with the gender roles of male, or female, or neither. I didn't mean to imply that it being an "internal property" meant it was biological, as I've been trying to explain - it's psychosocial. Edit: I think fundamentally, if you don't object to treating trans people decently like using their preferred pronouns and name, or getting surgery, I don't think it matters too much. I'm not an expert on the definitions by any means, my primary concern is opposing justifications to mistreat trans people, so if it's just a matter of terminology I guess my only suggestion is to read into what the relevant fields of study have to say if it's something you want clarity on.
