Transactivist groups and individuals have relentlessly targeted children of all ages - in schools, children's organisations, the NHS and to society's eternal shame, even children in care of the state. These powerful organisations have been led by the predominantly male born adults, many with autogynephilia. These men make up the powerful organisations who've (until recently) have been granted so much power over society.
Children have been gaslit with the notion that their developing uncomfortable bodies can be wrong, but a sex change is the solution. Sex change is an adult "interest" and the young have neither the insight or experience to navigate such an incoherent and dangerous to the young and impressionable, ideology.
Teenage girls are particularly susceptible via social contagion. Those of us who work with children know that illnesses like anorexia can spread amongst a peer group with social media speeding this up significantly. Hence teenage girls being the other group over represented in thinking their bodies are flawed. Accurate data can be hard to find as until recently transactivists defined research and data capture as "transphobic". Hannah Barnes book "Time to Think" is a good source.
Unfortunately the trans lobbyists have been immensely successful and attracted massive funding, including from the state. This has been misused in an attempt to remove fundamental safeguarding principles that should apply to all children.
There is now a massive pushback on all this with the two successive governments accepting the criticisms and recommendations of the Cass Review, this govt starting to put in place restrictions on the abuse of puberty blockers and "sex change" hormones for young people. Plus legal & social action against the intimidation, bullying and lies that have been used to enforce this ideology on an unconsenting public.
What has been done to children is unforgivable but it will sadly be some time before we see the charlatans who targeted the young like this, in court to answer for their crimes.
