Wholly agree.
Those 8 years have been spent with people trying to politely, kindly reason, sympathise, endless explain that they are not saying such things to be mean but because other people have needs too and that the dangerous bits don't disappear if you identify as them not being there..... it hasn't worked. At all.
The only thing that is going to work on this is unfortunately clear, firm boundaries.
And while some parents have actively enabled and found their own benefits and identities through their children's, plenty of parents have been threatened with social services involvement or worse, and have had zealous school staff gagging to enable their child in parental alienation as well as many less than healthy or stable adults online meeting their own needs through vigorously encouraging kids through transition. And those parents have been left with the awful option of going along with harming their child and by doing so at least have some hope of gently applying breaks or other thoughts to protect their child, and not losing them altogether. Some of them are MNetters, right here, still dealing with this daily.
This is a massive safeguarding failure on so many fronts. Massive. Historically so.
