Slightly off topic, but this guy (Ibn Sina) is a good example of what was accepted by Muslim (sunni) society a thousand years ago.  (this book, 'the book of healing', was published in 1027)

Avicenna often used psychological methods to treat his patients.[8] One such example is when a prince of Persia had melancholia and suffered from the delusion that he is a cow, and who would low like a cow crying "Kill me so that a good stew may be made of my flesh" and would never eat anything. Avicenna was persuaded to the case and sent a message to the patient, asking him to be happy as the butcher was coming to slaughter him, and the sick man rejoiced. When Avicenna approached the prince with a knife in his hand, he asked "where is the cow so I may kill it." The patient then lowed like a cow to indicate where he was. "By order of the butcher, the patient was also laid on the ground for slaughter." When Avicenna approached the patient pretending to slaughter him, he said, "the cow is too lean and not ready to be killed. He must be fed properly and I will kill it when it becomes healthy and fat." The patient was then offered food which he ate eagerly and gradually "gained strength, got rid of his delusion, and was completely cured."[9]


This isn't too far off from the techniques Erickson would use.  (he was way ahead of his time in other types of medicine, as well as geology, physics, inductive reasoning, and a bunch of other things)  Compare that to the types of things the 'Islamic Republic' teaches in schools.

Point here being... there's a huge liberal/conservative sways in culture, and by extension religious thought... so anytime you say 'this is a liberal religion' or 'this is a conservative religion', you're constrained to what they're doing at a particular point in time.
