You are simply ignorant of the facts. The autism spectrum is real. Some can function in school with an aid like my son. Those more affected can not. The difference is IQ. My son would have never made it through school without lots of help. He is now in the 5th year of a doctor of pharmacy program. He will be specializing in neurological medicine.
As someone who nearly got pigeon-hold into a diagonsis of autism, I am quite literate on the subject.
