The sad thing is that if non binary didn't come with the label, name changes and sometimes surgery, I'd be right behind it (as would most of us I'm sure).
Push away the stereotypes of girl/woman and I applaud you.
I feel it can't be a coincidence that this exploded at a time young women seemed to morph into looking the same, and highly glamorous.
I see school prom photos and think I could never have looked like that. I can't do the professional makeup, false eyelashes, hair extensions etc. And I'm not criticising that, some look incredible but I just couldn't do it.
I wonder if it's a lot of 'I'm not that so must be something else'. In the 90s we were in long shirts, tank tops and baggy jeans. It was perhaps simpler to be a girl if you view it at surface level only.
But age and experience teaches us none of those things are what define us as a sex class.
It's easy to see how it appeals to ASD girls but I feel sad they feel they need to change into something else rather than accept they are just as female regardless of presentation.
