What is the difference between a disorder and a 'disorder' in that case? When is a disorder really a 'disorder'? I tend to see classification and diagnosis as a pragmatic means to an end. The important part of defining a personality disorder or a mental disorder in general is to nail down a set of characteristics to effectively diagnose people that suffer from similar conditions and give them access to treatment and advice that may help them relieve the impairment and distress it's causing. Classification on this level should be largely unconcerned with whether the disorder represents some sort of fundamental deficiency of the brain or some rare personality trait that only becomes a problem due to a failure of society and social expectations. Not because social change to accommodate atypical personalities isn't desirable, but because it doesn't immediately help the diagnosed cope with the conditions they have to deal with in the present. Because of this, the disorder-'disorder' dichotomy seems wholly useless to me, at least without a clear definitional basis.
