My brain likes to elaborate theories. And right now, I'm wondering if Cass is not trying to criminalise giving puberty blockers to trans kids altogether.
Regarding the Jo case, her question was:
"I ask the noble lady the minister should her subsequent treatment be decided by politicians or by the clinicians who are looking after her?”
She may well be looking for a "politicians" answer, as in: politicians tell clinicians to stop all PB prescriptions altogether.
And now:
Cass’s main argument is that a trial is nevertheless necessary because some children are obtaining hormones or other drugs from private or unregulated sources.
Again, this is a problem that could be 95% solved by making PBs altogether illegal to give to a trans child. Some parents will still go ahead anyway, but for most, the criminalisation of the whole affair, after it's been proven with no doubt that PBs are bad for trans kids, should be enough to deter them.
Even this:
She says that carefully selected children, fewer than 5% of those attending the new NHS services, would be extensively assessed, approved by a national multidisciplinary panel and closely monitored during the trial.
is pretty damning. It's basically saying that they would experiment only on the most determined, who would likely get PBs another way anyway if not through this trial - and, crucially, who would have no reason whatsoever not to show a perfectly rosy result in the end. But if she expects, on the contrary, glum results, then it would be the biggest condemnation possible for PBs, if even the perfect subjets don't give good results.
At this point, I have to wonder if she doesn't have access to partial and unscientifically obtained but abysmal data about the poor results of PBs, which she can't use, and thus which she hopes to reproduce in a thorough trial. If that's the case, and she's asking only for a 12-month trial anyway, then it could be that the effects of PBs are even far worse, and far quicker in effect, than what we thought already.
