The outcome of all this crap is demonstrated in this film, also from the Beeb:

The young person who is the focus of the film regards themselves as being pansexual and non-binary. What I see in this film is a bisexual young woman, albeit one who is, or certainly has been in the past, unhappy and confused.
"Things like pansexuality and non-binary...do sort of deviate quite far from the norm," they say. Really? What is this 'norm', where does it come from and who dictates it?
She is dressed in the same way that I and many of my contemporaries dressed when I was 20, in the early 90s, i.e. jeans, Dr Martens, T shirt, shirt. Sometimes our hair was short, sometimes long. We drank pints of beer; bitter in my case. Yet we were all fully female young women, none of us doubted that. Blokes didn't either. And if you're gay, straight, bi: who cares?
God love her Mum, though. "I never really looked at you as being in a certain category, you were just Sophie."
