Label slappers topic
For what purpose would diagnosticians mislabel someone AS?
My GP wondered, and the psychologist who diagnosed me after extensive testing explained that he would still be paid, no matter whether I was diagnosed AS or not.
There is no ulterior motive here. I am not sure someone can self-diagnose, though a person may suspect s/he is AS, and share similar traits. There is no shame to being or not being AS.
Some people may be introverted, shy, be depressed or angry. These traits are not part of AS, though are able to co-exist with AS. There are many factors involved, and for someone to be sure it is always best to seek out a professional. And not everyone needs or wants this.
