There is some aspect of the brain that forms early, even earlier than birth in some cases, that leans towards male or female, and can be in between or neither, and having an opposite one causes gender dysphoria, which intensifies with age and sexual development as the body grows more different from what was subconsciously expected. I do believe non-binary has some legitimacy in this sense but I can't seriously entertain neopronouns. Some of these people with in-between may be binary trans too.
