Yes, you researched attachment therapies, but what about the factors supporting the RAD diagnoses? Where did you list the many facets of the disorder and their causes? Where was the child's behavior and the difficulties within the family discussed? I saw 'research' (one person's opinion repeated by you) saying that the extreme therapies can be harmful, but I didn't see anything saying why parents would resort to such 'extremes'.
This is truly a case of you needing to walk a mile in their shoes before passing judgement.
No, it is a case of someobody making a public appeal for help, and the public going by what little information is available. The reality is that it is perfectly reasonable to raise the issue that an extraordinarily rare disease, with a high degree of quack treatments, coupled with a CPS investigation, might suggest that a quack treatment is going on. I didn't pass judgement on anyone. You are the one who is using emotion due to your own experiences rather than logic.
