ItsGhoulAgain I think your post is why this debate could go on forever. When you hold your viewpoint, your argument for the right of selective termination, in the sense of diagnositc odds rather than multiples, is perfectly logical. I can't disagree with it. If the development of that life is a haphazard, random, cellular multiplication within a host, then the discovery of that process being disrupted and 'faulty goods' resulting should logically bring about a discarding of the 'faulty goods' and restarting of the process.
However if, as I do, you believe that each egg and sperm is part of a potential person, and that when they meet in the womb, a life has been created, albeit in no way ready to live independently in the world, and that life is a unique, unrepeatable being, then the conclusion is different. What results then, is that when deciding that a disability is an unacceptable outcome, you are killing that life.
Obviously, if that is regarded, as it is for some, to be an acceptable course of action, because the difficulties associated with caring for a disabled child and the difficulties the child themselves may suffer, then that decision will be taken. That decision is for the parents.
However, even at 24 weeks, most pre-term infants will die if not given artificial ventilation. Do we say they are simply 'hosted' at that point? Even many 28 week infants will have serious adverse outcomes without at least a little additional oxygen - what about then?
At 33 weeks, a baby is rarely able to breastfeed, and will require at least some tube feeds. Are they, too 'hosted'? And would it therfore be reasonable to abort a baby at 33 weeks?
At term, a baby will die if not fed and kept warm. Totally dependent.
Even at a year, a baby would not be able to find food for themselves to eat. What about them?
So if non-disabled babies are still totally dependent on their 'hosts' for such a long time, why is it reasonable to abort a disabled child for being dependant?
Xenia's post is of no surprise to me. I do not consider disabled people less valued, and the law says that they shouldn't be. But Xenia obviously feels that the disability discrimination laws are not worthy of even lipservice.
