You are so right. Autism-Aspergers is the flavor of the decade for incurable romanticizers. In the previous decade the flavor was bipolar, before that, ADD. The sort of reasoning went, if some bipolars are very artistic then bipolar disorder made then so. I used to say I could make a fortune betting that those who romanticize bipolar disorder have never had to see it in a loved one. You put it a lot more succinctly.
A study just came out that 90% of children diagnosed with autism actually have LYME disease. Many doctors have no idea that lyme disease is the number 1 infectious disease in the world. Tests are not very accurate for lyme disease, so you must see a lyme literate doctor, and there are not very many of them. Google lyme disease and autism to get many articles on the subject.
