Neurotypical v. Neurodiverse

I've been coaching and counselling suicidal auties and aspies for the past 21 years and am becoming increasingly annoyed with the psychiatric community for making us auties and aspies feel like freaks because we have autism. All the scientific papers written by psychiatrists make it sound like autism never existed until Kanner and Asperger wrote their seminal papers on infantile autism (Kanner) and autistic psychopathy (Asperger). Had they undertaken more than a cursory survey of the published scientific literature on the word autism, they would have cited papers of Profs. Bleuler and Hoche which were published in the American Journal of Insanity (1912) and state everybody has it. They define both autism and autistic as, "thinking, divorced both from logic and from reality". Neuroscientists nowadays tell us that everybody has autism, but don't refer to it as autism. They refer to brain wave development in children, from subconscious to conscious. From birth to about two years old, the human brain operates in the lowest brainwave levels, from 0.5 to 4 cycles per second. This they call Delta and, in adults, this level manifests during deep sleep. From two to five or six, a child begins to manifest slightly higher cycles per second, known as Theta brainwave frequency, of 4 to 8, and tend to be trance-like, living in the abstract, and show little nuances of critical and rational thinking, in other words, divorced both from logic and from reality. Between ages five to eight, brainwave frequencies rise to 8 to 13 cycles per second, called Alpha, in which the inner world of the imagination is as real as the outer world of reality, so they are still in the autistic mode described by Bleuler and Hoche. In this mode you can ask a child to be an aeroplane and two hours later he still is an aeroplane, divorced both from logic and from reality. From age eight to age twelve, the brainwave frequency keeps on rising, and any frequency above 13 cycles per second is called Beta. It represents conscious, analytical thinking. Okay. This is complicated, but what it says is, everybody has autism to around the age of twelve. Probably this is why, here in the UK, the exam to secondary education was called the 11 plus, and on Yahoo! Answers, you aren't allowed to become a member unless you are 12 or more. So, all Kanner and Asperger did was single out groups of kids whose manifestation of this universal condition was, in some way, different to other kids'. So, how come only those different kids were labelled autistic. Was it because Kanner and Asperger failed to undertake a professional survey of the published scientific literature on the word autism, or because they couldn't care less that everybody has autism?
