Curious Incident?

Remember that book? That lovely piece of fiction? Written by somebody who is not autistic?

Yeah, that.

It isn't a good reference material. For anybody. Because the person writing the book lacked any sort of personal experience with autism. And it's fiction. FICTION.

There are scads of autistic authors out there. Some of them are quite well-known. (And, to head off this argument, if you want to know how autistic people think, you really would want to read works by more than one autistic person, because not all autistics think the same way.)

Now, go forth and educate yourself.

Thank you.
