The Tavistock has a long history of unethical experimentation on vulnerable people that predates the transgender issue.
I am referring specifically to the "work" of some of their clinicians in relation to dissociative identity disorder (formerly multiple personality disorder) and to so called mental health professionals promoting the debunked belief in satanic ritual abuse (SRA).
The Tavistock and Portman NHS Mental Health Foundation Trust funded the development of the -centre for conspiraloonery and quackery- Clinic for Dissociative Studies, founded by the notorious quack Valerie Sinason and currently lead by the demented psychologist Rachel C Thomas.

Both Sinason and Thomas had previously worked extensively at the Tavistock as have many other conspiracy theorists promoting DID/MPD and SRA narratives.
My understanding is that there are many similarities between the Tavistock's involvement in SRA hoaxes, hysteria and quackery and malpractice and their involvement re transgender issue, specifically re the abuse of vulnerable, disempowered individuals.
In both situations it is difficult for people to stand up against the "true believers" in a culture where being a dissident could harm your career.
There are good people working at the Tavi as well as quacks. There are also well meaning professionals who simply believe what they are told in their professional training courses or who idealise their managers and clinical supervisors and have never thought to challenge them.
In fact one of the striking similarities between the Dissociative Identity Disorder / Multiple Personality Disorder narrative and that of transgenderism is the concept that rather than a "self" people consist of multiple aspects of the self who may be different genders and even ages.
There are various dubious models of "parts therapies" in which vulnerable people are invited to not simply explore different aspects of themselves but to give these aspects names and identities.
One notorious therapy of this sort is called Internal Family Systems. There are others.
