No it's not.
My daughter is an Asperger kid, and she has a very finely tuned sense of morals.
(She does guilt to the point where I worry about her getting ulcers)
No offense to you or your daughter.
Maybe I need to get out more. This is the first I have heard of it.
"Recently, some researchers have speculated that many well-known people including Andy Warhol, Andy Kaufman, Craig Nicholls, Rainer Werner Fassbinder, Glenn Gould, Gary Numan, Erik Satie, Nikola Tesla, Albert Einstein, Isaac Newton, Friedrich Nietzsche, Theodore Kaczynski, William James Sidis, Bobby Fischer, Steven Spielberg and Bill Gates have or had AS, as they showed some Asperger's related tendencies, such as intense interest in one subject and social problems."
If you ever read a bio of Bill Gates (a book on his life such as "Gates"-by Steven Mannes) you`ll notice throughout the book it mentions he has a tic of rocking back and forth and rubbing his hands together. When I was growing up, a neighbor of mine had a kid who had pretty severe autism who did the SAME exact thing!
