I agree. I also wrote below a message about this. Even the psychologist who diagnoses people for autism, doesn't know what a stutterer is thinking. For example, if a stutterer feels that he cannot say the sentence clearly, then he can skip words or sentences. He can shorten or change the sentence or take a pause mid-sentence (for scanning stutters) etc. So a psychologist who works as 'diagnoser' doesn't understand that this is stutter behavior and he will diagnose this person as autism.
