What blueroses said rings true...
I remember reading somewhere on this site that the site's founders had expected these forums to be full of people like them, and were surprised by the diversity of minds that flocked to these boards. That's been my experience interacting with other aspies, as well.
Now, having said that, I personally find these differences fascinating, and I do tend to be more patient with someone if I know he/she is on the spectrum. Also, note that greater deficits in communication do not necessarily indicate that someone is "lower-functioning" overall... It occurs to me that we may have many similarities in thought and experience, which can only be realized by overcoming differences in communication.
