I don't really know if it "should" or "shouldn't," but here are some... musings, if you will. Just what came to mind.
1. I don't typically tell people who don't need to know about my diagnosis. I guess they can tell that something's different, but I don't think they guess autism, right away. My original dx was Asperger's though, and I thought that the name itself was what bothered me, meaning the horrible joke that would come from it. I thought that if I could just say that I had autism, it would be much better. Then, when it got changed to autistic disorder... it didn't get any easier!
2. The whole disability thing. I've never been called "disabled" until recently, with the OVR and health insurance. Now, I am considered a "disabled" or "handicapped" adult. It frustrates me greatly. Am I disabled when it comes to the world of professional social interaction? You bet. But hey, want to go for a run or read a book or take a test on just about anything? I can whoop your butt. Now who's the "disabled" one? Point being, it depends entirely on the context.
