Two things that occur to me (remembering that I have Asperger syndrome, that so does my husband, that both hubby and son are also dyslexic, that I have arthritis and am often needing pain control plus a fair amount of help from others, etc).
First - is it ok to kill people because their perceived quality of life isn't so good? People have debated this one long and hard and the answer is always 'no' in a civilised society. If having a disability that may affect quality of life means people shouldn't be alive, who'd like to pick up the first shotgun or the first syringe with the lethal poison in it? Someone on this thread made a very valid point about the abject misery that many people live in through poverty, drugs, alcohol, self-harm, eating disorders, mental illness etc. Yet no-one's suggesting death for them. Death is reserved for those who are disabled. I find it interesting. And scary.
Second - if you're born with a disability, believe you me, you get used to the world being the way it is for you, and it's not that bad. The sun doesn't stop shining on us, the bird don't stop singing for us, the flowers don't stop growing for us to look at, the tv doesn't stop working because we're in the room. Our lives are much the same as yours are, with the same good things in them even if we can't be international footballers etc.
What hurts the most is ignorance and neglect and cruelty. And no 'shotgun' in the world held to the head of a person with a disability before or after birth is going to change that. Society has to change it. Society has to fight for basic human rights for each person, for basic effective pain relief, for basic help. These are not impossible dreams, they are a right. Yes, the authorities can make life hell...but...
...If a child or adult with a disability is having a dreadful and unfulfilling life, it Isn't Their Fault. It's the fault of the world around them. I don't get why people see the solution as "they should not exist". If I have a terrible journey to work every day, I don't need to be killed, I need someone to sort out the traffic problem.
Why is us not being alive the solution to any of this? Seriously?
