I subscribe to the view that gender - as a distinct and different concept to sex - is largely obsolete and should be done away with. To be honest, im not sure exactly when 'gender' (in its current concept previously stated) actually became a thing. It seems to have happened at some point in the last ~15 years and now is accepted as a thing, but I dont really see the point.
If we take gender to have no relationship to biological sex, then my question is simply: what actually is gender then? The best thing I can come up with is that its a set of stereotypes, preferences, expectations and opinions that are associated with men or women (which are the main two possibilities for biological sex, incidentally). This sounds an awful lot like simple stereotyping, but given a more modern and socially accepted framework. In a truly modern, diverse, accepting society, you should be able to treat each individual as to their needs, rather than needing to label and pigeonhole people into gender identities and such.
Unfortunately we (society) have recent habit of wanting to attach labels to everything - much like we do with neurodiverse individuals. Labels can at times be helpful, but they can also be unhelpful and damaging. I dont believe the concept of gender identity serves much purpose, in this respect.
I caveat all of this by saying that I have no experience of gender dysphoria. I enjoy bubble baths and fruity cocktails, but have never considered those to be mutually exclusive with being a man. I am a man because that is my biological sex. Beyond that, I am simply me, and I have my own preferences and opinions on the world which may or may not agree with any given stereotype or label at any given time. If someone else gains something from classifying or 'identifying' as something, or by transitioning from one sex to another, then more power to them - frankly it doesnt affect me. I just dont really understand the purpose any of it serves, and dont think it is an especially progressive way to form a society.
