Today I read a post on a Dandy-Walker forum by a sibling of a young man who lives with Dandy-Walker asking parents to consider abortion more seriously as the way to go after getting an in-utero diagnosis. She defended the position that practically all doctors push for termination as the preferable option.( I have yet to come across a DW family who were encouraged to welcome the baby by an obstetrician) Her reason for this request is that she wishes her mother had aborted her brother because then HER life would be better.
I replied that they could eradicate every known illness in that way. By killing every blind person, is blindness then cured? Of course not, you just have a lot of dead people and a lot of doctors who have done something which has no place in medicine.
Quality of life is not for us to determine, when I was pregnant with my baby who has DW 'quality of life' was all we heard about. The doctor gave the worst scenario, presented in a very brutal, un-compassionate and unkind way. She gave the worst scenario, but failed to present the equally possible best scenario that these babies can do amazingly well, that the love they carry along with them will blow you away, that they will cause a ripple impact of immeasurable good across the world - something very few of us can claim to have achieved with our eugenically acceptable lives, least of all doctors who march these precious babies off to have their quality of life removed from them, sometimes within hours of diagnosis. One couple I know were even offered an abortion in the Ultrasound room (which I'm guessing is illegal in any country) and were pressured to the point that the Dad placed a formal complaint with the hospital.
There is no difference. Abortion has no place in medicine, it is not medicine and ultimitely no good can come out of it.
