You know, she says an awful lot about what gender identity isn't, but very little about what it is. So far gender identity isn't related to appearance, hobbies, genitals, surgery, hormones, and clothes. It sounds more like she rejects the idea that gender exists at all, as claiming to be male or female is essentially arbitrary. You can look and act and have your bathing suit parts like Nick Offerman and claim to be female and that's just as valid as a person who takes hormones and gets surgery and makes an effort to present as female, according to this logic.
