A Cure!

...Is actually not something I'd ever want, nor is it something I believe will ever be found.
Autism is not a disease. You can't just get a shot or take a  pill that will destroy autism like you can with the flu. Autism is a way of thinking, part of the way your brain works. There's no pill for that. Maybe we'll be able to alter a brain to cure autism in the distant future, but I doubt a procedure like that can ever be considered safe or even legal.
Another thing is that I'd never want a cure. Asking to cure autism is like asking to cure comedians of being funny, it's taking away a huge part of their personality. I see things differently than most people, and I never want that to go away. I love the hum of electricity, the texture of a soft blanket, and even the way the light hits a gravel road. These are things most people ignore, but I find beautiful. Every negative of autism is worth it to me just so I can be moved by the beauty of things others find mundane.
I'm not saying that there's no reason for treatment in some cases. I occasionally take anti-anxiety medication when things overwhelm me, and there's nothing wrong with that. I believe that some autistic people, especially at the lower end of the spectrum, can really benefit from treatment such as classes on social skills and some medication where the benefit outweighs the side-effects. I just don't think trying to wholly remove autism from a person is right, or even possible.
Saying you wish someone didn't have autism is like saying you wish a non-autistic person had been born in their place. As I said before, autism is not something someone lugs around behind them like a suitcase. It is part of our brain, present in every thought, and the color of our world. The day I want to go without Asperger's is the day I want to go without skin.
