"Results In the sample, 14 516 children were diagnosed with ASD, of whom 5689 had autistic disorder."
Put another way subjects were not excluded from the study because they were not high functioning, Asperger's subjects. For this fact alone the study is ground breaking, hopefully shattering the dominant trend of recent years of creating a false " pure autism " by excluding the original, classic autistics as study subjects of whom the " vast majority " suffered from intellectual disability (Yes Emily Willingham and Jon Brock, I said "suffered from").
The "it's gotta be genetic" crowd will see what they want to see. They will see the genetic half of the autism causation equation and will ignore the environmental half, pretend it doesn't exist as they have done for so long. Likewise the inclusion of a proportionate number of subjects with classic autistic disorder will, if discussed by the autism is beautiful crowd at the Thinking Persons Guide to Autism will if noticed at all be mentioned as a reason to criticize the study. Still, the study does offer more hope of breakthroughs in the rigid mindsets who forbid honest discussion of autism realities be they environmental causation or the harsh realities associated with classic, low functioning autism DISORDERS from which so many who carry the Autistic Disorder diagnosis actually SUFFER.
