I just took a look at Amanda Baggs website. My impression is that she has some other diagnosis - I won't even venture a guess what. She is definitely gifted. But I do not buy a diagnosis of autism.
Anyone ever hear of Temple Grandin, PhD? She is an adult with autism you can respect and believe. I just recently saw her speak - she is amazing. Read her work. Find her books on amazon. Try "Thinking In Pictures" if you want to learn about what it is like to have autism.
I repeat, Amanda Baggs is NOT representative of the autism community. She *might* have aspergers. But then again, a lot of highly intelligent people who want an excuse for behaving badly are "self-diagnosing" with asperger's. For some reason that diagnosis has become a badge of honor in some bizarre circles or subcultures. And Amanda Baggs is not associated with any mainstream autism organization or agency that I can see. See for yourself on what she now offers at her website:
