I am strongly "pro choice" - i would allow abortion on demand upto 21 weeks and after that with medical need. I think the way we deal with children who have very poor quality of life and very little chance of living beyond a few months after being born is really poor.

None of this is incompatible with saying that the "clump of cells" is precious and worth preserving, and that parents should have support before, during, and after pregnancy to help this child.
