Following this early identification of ones own sex, children come to realise that they cannot change sex. Prior to this, they think that even though they are a girl, they can grow up to be a man, have a beard and inseminate a woman
Except adults are now trying to stop them realising this. For a number of children set on this cross-sex identification path by their insane parents, they're trying to keep this lie going.
Presumably this will all get explained properly to a child in time so they can give informed consent to the puberty blockers.
Right? Right?
But how much psychological distress is going to be caused when they eventually realise they won't really be the opposite sex? That their parents have been lying to them?
I remember two instances of lies about sex encountered during my childhood. No identity issues of my own, but they still haunt me just from finding those in authority lying.
First was a sex education book which talked at some point threw in that the man and woman had to be married.
This freaked me out for quite a while, as I couldn't figure out what marriage had to do with anything, and I was getting worried that there was some weird physical ritual involved in a marriage that no-one was telling me about. The book didn't explain why the marriage was necessary. I don't remember how that confusion got resolved, but I remember the confusion from the insane category error.
The second was reading about a "sex change" operation. This also threw me because it really didn't fit with what I knew about human medical technology. I didn't think we could do anything that fundamental to a human - if we could do that, why was everything else so primitive? I was left wondering if there was some (clownfish-style, I now know) mechanism latent in the human body that could be triggered in some way. I later found out they were just talking about cosmetic surgery, and I was so cross.
And this is just me in the 70s/80s, encountering fairly mild falsehoods. God knows what it must be like to be encountering this wall of total insanity, and actually having some personal issues in the area to work through!
