I'm really concerned that these people are setting themselves up as experts and trainers when they seem incapable of evaluating and critiquing what has gone on in the case of J.
Which I think is the root cause of their fear, that your concern will become the general public's concern. That cold, hard shard of truth that lives inside your head, even after years of believing your own hype... can be very jabby. Hence their misrepresentation of the judgment IMO, in an attempt to control the narrative regarding the motivations of the judge to arrive at the conclusions he did.
Judge perceived as massive, out of touch bigot
Mermaids teflon coated regarding any fall out from their actions in this case. Best case scenario, lemonade from lemons, they are essentially handed a springboard to get more money, attention, exposure and room to root themselves even deeper as the self appointed "most experty experts".
Judge perceived as even handed with justifiable, grave cause for concern -
Mermaids exposed to searching questions as per how they missed a child being abused right under their nose. And to what extent did they (albeit in a state of ignorance/blinkerdom) participate in, encourage and support the abuse.
And if they missed this case (with its evidently unstable mother, who was none too subtle and set off alarm bells left, right and centre in less blinkered circles) what price they have been able to spot and avoid encouraging less obvious cases of forced transing performed on small children.
There is also the question as to what steps they take/fail to take to ward off "identity building via the niche" in the parents they work with.
It's not exactly a secret that in niches like this some parents, who have long felt they would like to "be somebody", find they can be something "special", something "noble" and gain status via the niche.
No longer bog standard mum/dad, but instead parent crusader for X rights.
Where the moderate vocabulary of a boringly normal parental life gets replaced with more Hollywood, action packed terms. Like hate, oppression, "actual violence", colonisation & persecution. Some of them even find suddenly they get listened to (media, giving talks, microphone at marches). And they like it. It's so much more exciting, interesting and "feeling important" than life used to be.
The issue is that once a parent gets a taste for that, it can be hard to give it up. So the child is no longer at the centre and there isn't necessarily the same degree of parental flexibility about the child's feelings about X anymore. The kid can get stuck cos the parent (sub consciously or otherwise) fixes them in position cos they, the adult, don't want to give up what being an "X Parent" has offered them in terms of a freethinking / swashbuckling / hugely victimised identity.
It's certainly not all parents that are susceptible to the above. But by the same token it's not a vanishingly rare group that are. People who set themselves up as experts in any kind of "parenting niche" are aware of it (unless also suffering from the syndrome and unable to see it in others) and it behoves them to be on the look out for it, for the sake of the kids. IMO.
