The people who see disability as something to be feared/killed off should try reading books like "Dasha's Journal" by T O Daria, or "The Myriad Gifts of Asperger's Syndrome" by John M Orwitz. Such positive books, showing the good points of each individual with a disability instead of just a depressing list of things-they-can't-do.
Books like that have made such a difference to me and my outlook on life, realising the things I'm actually better at than many other people. (I can find visual information at lightning speed, I can hear when a piano is even slightly out of tune, I can spot ceiling lights that are about to fail well before other people, I can concentrate on something for impossible hours without tiring, etc. I just couldn't explain any of it beforehand.) To give one example, most children with AS have extraordinary abilities of one kind or another - it's just that people are so used to thinking "their way" that they miss these abilities completely, because they misinterpret them , or lack the skills to hear what their child hears, see what their child sees.
It's like the child who would scream at her bedroom wall for hours. The parents put it down to being a destructive obsession, but in reality she could hear a failing electrical cable that was well on the way to being a fire hazard. When it was investigated, the electrician said that she'd probably saved their lives.
Not every child will have an identifiable amazing ability, but I do wonder how many are missed because most people lack the skills to realise what's happening.
As human beings we all have things we can't do and things we can't commnicate that well, or things we find really hard. It doesn't have to define us and be the only thing that matters. I wish they'd realise it and stop treating almost all people with disabilities as if they don't deserve to live on the same planet as supposedly more perfect people, or as failures or something broken. sigh
