The suicide rate among LGBTQ is also some outrageous multiple higher than average and in the not to distant past that was also a bona fide psychological diagnosis. You see the intrinsic problem with codifying anything out of the ordinary as a "disorder"?
That's a slippery argument. At the low functioning end of the autism spectrum are behaviors like tantrums, compulsive violence towards self and others, and behaviors like fecal smearing. We also need to be careful not to ignore clearly disordered behavior. That is not compassionate towards the afflicted, either. If a disorder can't be labeled a disorder, the patient cannot be treated.
