One of the things about all these mainstream psychology arguments is that the phenomena are presented either a pathological condition with associated brain chemistry or a simple psychological difference of little consequence. There is no room anywhere in these discussions for person's condition to shade between cognitive difference that can be quite useful in some situations and related behavior that might be seen as a serious dysfunctional in other circumstances (and people).
I thought that the DSM's criterion for pathology vs. eccentricity was whether it negatively effects the person and/or those around them. Treatment is only indicated insofar as the condition is actually causing a problem.
