I have no doubt in my mind that some of the most evil insanity is committed in the name of religion as it gains 'asylum' and therefore immunity in the name of religion. And how interesting is the different connotations of the word 'asylum'.
You're not by any chance a literary studies specialist? A deconstructionist? Yes, 'asylum' is another of those weasel words used by weaselly people....
Very sad to say that it seems to me that these 'diagnostic' criteria will never materialise and the research results will be consigned to some dusty shelf somewhere obscure.
I imagine that the problem with such criteria for reglious fundamentalists is that they will probably equally apply to a range of other psychopaths (politicians, doctors, judges, police, teachers etc) who hold positions of high authority. And that'll never do!
You might be interested in a talk by a former UK cabinet minister about narcissism/psychopathy amongst politicians on YouTube (Dr David Owen: The Hubris Syndrome) Very pertinent to this spiritual abuse discussion. Dr Owen was a medical doctor and neurologist before he went into politics and diagnoses a lot of politicians with this same disease which inflicts cruelty and pain on others whilst leaving themselves sublimely untouched.
I think the point is that anyone who has a predisposition to dictate to others, no matter how they wrap up their motivations in weasel words ('devotion to God' or 'the improvement of society', it's all the same!) is probably veering close to the psychopathy/sociopathy/anti-social personality disorder end of the spectrum.
Perhaps to make a distinction between 'religion' and 'insanity' it's also necessary to call up the need for a clear distinction between right and wrong, good and evil in regards to how adherents behave. Religion isn't wrong per se, it's the cruel, manipulative behaviour of many of those who profess to practice it. Ditto politics etc. Since Western societies did away with the clarity embodied in the Commandments and the instruction to love thy neighbour as self we just haven't had any decent, effective yardsticks.
But it also occurs to me that if we could formally nail the cruel, manipulative behaviour of those who seek and endeavour to impose religious - and secular - authority as, say, Fundamentalist Hubristic Insanity, DSM6, pp 659-830, it may at one fell swoop do away with many of the diagnoses of 'mental illness' too many others of us have to bear. (I can't remember how many times I've been told by MH professionals and read that 'PTSD is a normal reaction to abnormal events'...)
Sorry, I didn't mean to begin a dissertation!
