Lol, I think many doctors would be clamoring to rename it if it were called “Pat the Bunny syndrome”. Renaming is part of science, unfortunately, just like how “manic-depressive” became “bipolar” and “multiple personalities” became “dissociative identity disorder”. The only distinguishing feature in the DSM between classic autistic disorder (what you call autism proper?) and Asperger’s is whether or not there has been a delay in the acquisition of language, which yes, manifests very differently. As for the average person associating autism with no communication, you’re right, they do, I run into it at work all the time. I had a teacher laugh at me one time (over a pdd nos student) saying he wasn’t autistic, and I had to point out to her the poor eye contact, the lack of reciprocity, the repetitive behaviors, taking things literally, difficulties transitioning, and the toe walking, even though he can communicate. I work with kids and adults on the spectrum, some are very happy about no longer being “separated” from autism with the Asperger label and others are having a very hard time due to it becoming part of their identity (you know how it is with transitioning and change). But from an academic standpoint, the new labeling makes sense to me.
