One of the most disturbing things I've seen evolve from this is the implicit treatment of children as though they're mini-adults and they just need time to become aware of and gain control of their body. Once that happens, what they say is gospel.
In doing this, we're to blindly accept a three year old boy saying they're a girl, or it's fine that children are exposed to kink because they just want to pat the [rubber] doggy. It's why so many people got the ick (sorry, Love Island ref) when BBC Women's Hour asked if there should be 'age-appropriate porn' for teenagers, because we recognise that no, they're children, and we prevent them from having access to adult things (tattoos, marriage etc) because they are not yet old or mature enough to understand what is involved, and what the consequences are.
In treating children as mini-adults, the unscrupulous individuals like gender therapists, endocrinologists and surgeons are laughing their way to the bank. In the Bell v Tavistock appeal, the barrister for Tavistock wants the initial judicial review reversed as this would allow for a child to be autonomous - to consent to experimental treatment. It doesn't take a genius to figure out the mental leaps that some take, to say that if an eleven year old can consent to puberty blockers, then surely they can consent to sex.
