The ICD-11 explicitly mentions non-disordered systems
[ID: A screenshot from the ICD-11.
Orange text: "Boundary with Normality (Threshold):"
Black text, preceded by a bullet point: "The presence of two or more distinct personality states does not always indicate the presence of a mental disorder. In certain circumstances (e.g., as experienced by ‘mediums’ or other culturally accepted spiritual practitioners) the presence of multiple personality states is not experienced as aversive and is not associated with impairment in functioning. A diagnosis of Dissociative Identity Disorder should not be assigned in these cases." /end ID]
The example given is spiritual systems, but again that's just an example. The main point is that
The presence of two or more distinct personality states does not always indicate the presence of a mental disorder.
So if people could stop harassing non-disordered plurals for having an experience of existence that is recognised in the ICD-11, that would be great!
Plurality is not always a mental illness (this is specifically the page for dissociative identity disorder btw), so please just let plurals exist, as they do, without harassing them for not meeting the diagnostic criteria for DID, or not identifying as having DID.
