Judging from this discussion, there is no need for arguments in favour of testing to be aired. As poster after poster has shown, people are very familiar with the case for testing. They are well able to articulate it Anne it is clearly the majority view. In that case, to ensure a balanced argument it is the case against that needs to be heard.
But Philips's programme was clearly a personal view - and she was reluctant to make the programme herself because she's not a documentary maker. It's just that she couldn't get someone else to do it. Perhaps the case for testing should have been part of the programme.
In any case I do think it is significant that all the posters on this thread who themselves have children with a disability (at least those who have declared themselves as such) have in general liked the programme.
I know that caring for a child or adult with a disability can be a burden that feels and is intolerable. But surely that is an i argument for better care for the disabled and their carers by the whole of society. If we really valued caring we would support carers better. But do the difficulties of caring for someone mean their life has no value - either to themselves or to you? The size of your vocabulary or your continence or mobility or behaviour doesn't determine your worth as a human being.
Encouraging the attitude that the birth of a baby with a disability is an avoidable tragedy suggests very strongly that their life is without value. And that, surely, is completely, profoundly wrong?
