I feel like I need to clarify that I wasn't suggesting DSM is wrong on autism and needs changing just because I personally don't identify with being categorised as disabled. My point was that DSM has been misguided on a whole gamut of conditions through it's various iterations, hence the periodic updates and changes to diagnostic criterion.
I think it's inevitable the DSM description of Autism will morph eventually, but I'm making no claims about how exactly.
The issue I have with constant references to DSM is that it you tend to become defined entirely by the medical model if you do that. It's no different with any of the myriad of mental health conditions DSM lists. If you have involvement with psychiatry you might have an idea of what I'm getting at. The medical model is used to evaluate your entire life, and every aspect of you is viewed through the prism of DSM. I read a psychiatrist report about me once that said that because I always presented wearing black this was a reflection of my mood and personality type. That is absolute nonsense. I wear predominantly black to simplify laundry. It means I can throw everything in the wash together without sorting my clothes. There's no scope for recognising that within the medical model though.
I consider my autism a minuscule part of my life, I really don't want to be viewed as an 'autist' and nothing else, or be considered in a way that means people attribute everything I do, who I am, how I act, and all of my behaviours to my autism. I'm a person just like any other with aspects of my personality that are nothing to do with autism. So I reject being defined by black and white text in a book.
Again, people with diabetes, for example, are often referred to as 'diabetics', but nobody tries to imply their behaviours are shaped purely by their medical condition, or that all people with diabetes are the same just because a book defines diabetes.
The biggest thing for me though is just the stigma that goes hand in hand with having a recognised condition defined by the medical model. People who are not medical or care professionals stigmatise you because of the simple fact you have a diagnosis. They know nothing about what that diagnosis actually means, but it's written down in a medical book, so it must be 'bad', you must be 'ill', and you're probably dangerous to boot, right?
