I want to make sure I understand - You think that autists are not real humans like you are, because they seem weird to you, and too smart?
It sounds like you don't mean it as an insult, but if autists said that normal people were probably not actually human, would you take that as a compliement?
Autism is a brain disorder - most likely a combination of genetics and trauma from external factors (such as toxin exposure). But you are thinking that autists are the result of some cloning or AI or test tube babies?
