I'd say it's not necessarily a 'complex' issue but it does add a layer of complexity to my life. My DD came home from High school last year saying somebody new had started at their school, I asked whether it was a boy or a girl and I could sense the atmosphere change. It was a combination of me:
a) realising as soon as the question came out of my mouth, that this could be deemed to be a 'controversial' question - why on earth is that of interest to anyone, anywhere - why is it important? Duh Mum you're so transphobic etc...
b) I could visibly see my daughter recalibrating her thoughts to not instinctively answer me with girl or boy because she' s had it drummed into her that it's wrong to assume someone's gender identity' and she obviously knew that this person did not present themselves as a boy or a girl or there was at least a question mark over it.
I supressed my frustration when she said 'she didn't know' and said 'well what sex do you think they are?' impressing upon her that I know they may choose to present as another 'gender'. But she was cross at me even though she really does know the difference and the importance of that difference in certain situations and circumstances. She knew their sex but thought it was better, for some reason, to make out that she didn't know, or didn't care (which I don't believe!)
The name didn't give any clues but in the past 6 months the same child has changed their name once and then changed back to their original name and has just changed their name again. My DD says everyone just accepts that they are quite a troubled individual and that they just go along with whatever they say they are but know that they'll probably change their mind again. They are, of course, pansexual which you probably would be if you are exploring all options. But the school is cool and supportive (and there's quite a bit of apologising going on when some teachers haven't had the latest update and misgender/misname them) and the pupils are all good too.
DD and I have had some good chats though. She's asked me what I would do if I brought this person home and I said, I'd ask them what they wanted to eat? What subjects they like, do they have pets etc...It's not the individual that's the issue, it's the swirling, obfuscating, totalitarian, divisive notion of identity politics and gender stereotyping that steers and influences all our lives that's the problem.
Oh, and the child is so obviously a young female human that currently feels more comfortable identifying as a young male human. And I want to give them a big hug (but obviously won't).
And I know this is probably not specific to Scotland but I sense that Scottish women are going to have a harder decision to make at the ballot box when the options are so bloody limited.
