I like it. The assumption of psychological causes of illness in general is another thing that has I suspect never been adequately shown to be safe or correct. Nobody is really looking for harm related to this even though it's very easy to find patient stories of harm.
People may object to mental illness diagnoses because they are often an instance of bad medicine and bad care. We need less talk about "stigma of mental health" and more genuine efforts to recognize how mental health ideas are harming people.
