Definitions are much too narrow, there is so much overlap, ultimately though therapeutic methods don't differ quite so wildly. The handful of conditions he was displaying are common differential diagnoses with very similar treatments.

However, there are stigmas attached to certain diagnoses and not their differentials so some people prefer less negative labels.

In my experience with world class psychiatrists your views are a little outdated, generally the more academic practitioners are much more like Dr Barron.
