I agree with SweetLeaf. According to what I have researched Asperger's Syndrome is part of the Autism spectrum. People with Asperger's are usually at the high end of the spectrum. "Classic" autism covers a lower part of the spectrum. I first heard about classic autism in the 1970s or 1980s. I found it interesting as a disorder, but did not see myself in it. Less than 10 years ago, I came across info about Asperger's, and it was like fire works going off in my mind. I saw myself in the very first article I came across. I continued to read anything I occasionally came across about Asperger's over the next several years. Every article was like a mirror of my situation, so I finally started doing deliberate research into Asperger's, and eventually took an online test. I tested positive for Asperger's--no surprise. I eventually found WP and lurked here for over a year, before joining. This site has been very helpful to me.
As for questions about the difference between the different autism conditions, they are different enough for me to not see myself in classic autism,and other versions than Asperger's but there are similarities that make it clear that they are all related. I think the spectrum mode of describing the different manifestations these disorders take is a good way of describing them because it covers all of them while allowing room for each to be separately accounted for.
I also don't see any reason to quarrel over it.
