Indeed.
On a more general note: I'm much more inclined to examine the (extremely-difficult-to-get-right*) issue of the Tavistock (and best practice approaches for minors presenting with transgender identity) by examining the actual official report, which had access to everyone and everything (good and bad).... rather than a book written by a journalist with an editorial slant and a propensity for listening to self-selecting interviewees with axes to grind.
* And it's important not to lose sight** of the fact that in many - maybe even most - instances of interventional treatment given to minors presenting with gender dysphoria, those treatments have led to positive therapeutic benefits and long-term successful outcomes. The incontrovertible fact that there's still a paucity of evidence from which to measure & compare outcomes, and thereby to tailor treatments to produce optimal outcome success.... a) doesn't in any way mean or imply that, in overall terms, the treatments given to minors over the past several years has been clinically improper, and b) means that clinicians will have no option but to use their clinical judgement (along with overall guidelines) to make decisions on treatments, up until sufficient evidence comes forth over time to add an evidence base to those clinical decisions.
** Though it's interesting to note how the recent "revelation" about the current (obvious) lack of a statistically-significant evidence base in this area has prompted certain commentators to claim that this factor, in and of itself, both 1) invalidates the treatments currently being offered in places such as the Tavistock, and 2) in some way imputes incompetent (and perhaps even malevolent) motives to the clinicians who've been making extremely difficult decisions with the aim of helping the patients under their care.
