For every "treatment" or remediation in autism-land, there are both fervent believers and detractors. For every person helped, there's another harmed. Perhaps, just perhaps, in some cases, it's not the therapy itself, but the person conducting the therapy that makes it a problem.
There are bad apples in every field, people who misapply therapies, others who use their position to abuse, and others who are so incompetent as to be dangerous. Nowhere is this more evident and problematic than in the disciplines that are involved in helping people--be it in academia, in psychology or in service-related fields.
