The ruling is correct. It's almost impossible to discuss these issues without getting emotive but and the end of the day the question is reduced to legal body autonomy.
My brother has DS. He is not and has never been high-functioning. His childhood was extremely difficult. He's never been fully verbal and did not walk until he was 12. He has needed round the clock care his entire life. He is now in the latter stages of dementia and is once again no longer mobile. I am his only living relative now. He doesn't know who I am. I saw first hand the difficulties and the sacrifices my mother made. When all her friends were dealing with children becoming independent adults, she was essentially still parenting a toddler, well into her 80s. She died terrified for his future care, which I have taken over.
I'm not saying my brother has had a tragic and pointless life. Our memories are full of happy and joyous occasions. He had a wonderful personality until the dementia kicked in.
As another poster in a previous situation has said. If I had ever been in the situation where I received a positive test for DS in pregnancy, I would have terminated. I know the reality of the care needs and would not have taken it on. Crucially, I would have had to sacrifice the care for my brother in order to look after my own child.
And this is the crux of the matter. Everyone's situation is different and the only needs that matter in pregnancy are that of the pregnant woman. Many women will continue with teh pregnancy and that is a good thing. Others will not, either because they know they cannot handle the situation; because they will not be able to afford to give up work to become a full-time carer; have no option to convert their home for accessibility, or because they have other children or dependents with complex needs and need to devote time and energy there. All of these situations are valid and all of these women deserve the right to choose.
I will defend to the death, the rights of people with DS and other disabilities and am actually involved in several groups lobbying for better care facilities, better medical understanding, and end to discrimination etc. My stance on abortion does not change this one bit. I am fiercely protective of my brother yet I have had abuse levelled at me in the past when I've voiced my opinions on screening and termination. Fighting for a woman's right to choose and fighting for my brother's right to receive care are not mutually exclusive things.
