Temple Grandin is one of the very few would would speak F2F. There are many others who write but will not give F2F interviews or make appearances. I agree with @iwamoto in my skepticism of Jenny McCarthy. Autism is slightly treatable in its more highly functioning forms, such as AS in children and teens, but is definitely not curable or reversable. She is dealing in false hope. Anyone who claims to have had their autism “reversed” was probably misdiagnosed in the first place.
Autism is a condition related to the basic structure and “wiring” of the brain. Connections do not occur in the same way as with neurologically “normal’ people. To some extent we can learn how to simulate “normal’ behavior, such as faking eye contact, maintaining a “neutral” body posture and learning when to “shut up” about topics that are of no interest to others. Such things are learned by rote memorization and pattern recognition, but without understanding or any real degree of empathy. To many of us, the rest of humanity, at a face-to-face level at least, are merely obstacles to our privacy, comfort and material well-being. We must learn that “real” relationships are forever closed to us except under the rarest of circumstances.
