I think it is because everybody can accept that blindness is a defect. Eyes are supposed to see. If they don't they are broken. When it comes to autism, at least the more mild forms, it is just a range of characteristics that can be found in non-autistic people. Somebody is less social or can't understand sarcasm or whatever, well that doesn't mean the person is autistic and it doesn't mean they have a medical problem. We don't say a guy who is 5 feet or 6 foot 5 inches has a medical problem. We say that is fine and within the "acceptable" range. Somebody who has dwarfism does have a medical condition. I think autism is the same. Those with mild forms of autism may see it as an attack on them or their characteristics. Not sure if that made sense?
