My mother works with children that have fairly advanced autism & I've had the pleasure of going to work with her for an entire Summer.
I find autism fascinating. In some cases it leads to Idiot Savantism (where a person who can do almost nothing can do one thing - like playing the piano -
extremely well). I find it interesting that someone with advanced autism, being unable to express themselves normally, compensate by being able to express themselves through art.
I don't see autism as a disability at all. Autistic people think just as any human would, the problem lies in reactions & responses. Some of the autistic children I've worked with have heard me say "Hey there, what's your name" & understood exactly what I've said, but have been unable to express that understanding & instead stare blankly or seems to be inside their own mind.
And this in turn, compounds the often-found anger in autistic people. How frustrated & angry would you be if you had your same mind, but were unable to communicate normally?
