I find the whole business both worrying and tiresome. And I have had various trans friends throughout my adult life (so from the late 80s). I've got at least half a dozen trans friends now (including a couple of non-binary-identifying. TBH I think that is a little bit silly and attention-seeking, but as they are otherwise lovely people, I'm prepared to put up with it in the same way as I put up with lovely people being eg practising members of a religion, or sports bores.)
Yet I have seen so much horrible, spiteful, misinformed or dishonest, scaremongering, self-righteous, obsessive behaviour from various individuals on either side of the debate that I try to keep out of it.
Yes, there are still conversations to be had and things to be considered with regard to how gender is experienced, performed and controlled. The idea of a gender binary has always been about reinforcing male dominance over women, which is something some people on the 'trans rights now!' side seem to forget or not know.
There's nothing wrong with cross-dressing because it turns you on, either. Or with having more than one 'identity' (I am really, really used to people who have more than one 'self' and are entirely rational about it - people who are performers and have a stage persona, authors who have an 'author persona', people who spend their weekends being historical peasants, or wandering faeries... or just dressing in fetish wear and being a fantasy made flesh.)
My concerns are rather more about things like: women's sport (even though I don't like sport much myself). It's going to need to be re-thought, and the rules are going to have to change. And my other concern is the possibility of corporations, having got a ticking-off for their gender pay gap, suddenly announcing that 30% of the men-in-suits who make up the Board actually 'identify as female' so no gender pay gap, nothing to see, nothing that needs to change.
