Yes, I know my views on this matter (explained often enough passim) are well out of step with most other peoples\’ but if viability is the guide, if someone is not human if they cannot live outside the womb and is if they can, well, this seems a pretty strong argument:
The data, for births in England and Wales, showed that eight of the 152 children born after 22 weeks\’ gestation lived for a year or more.
At 23 weeks, 44 of 283 children survived. At 24 weeks, almost half – 198 of 474 – of babies survived. Of the 201,173 abortions in England and Wales in 2006, 1,262 were at 22 weeks or more.
Use those odds of survival: some 5% or so at 22 weeks rising to 40% ish at 24 weeks. And again, use viability as the guide to whether this is a human with rights or not.
Does someone (or if you prefer, something?) who is 5% human have a right to life? 40%?
