The UK position is different to that of the US and represents a middle way compromise of the competing rights of the woman and the baby/foetus.
It means that most UK women who “needs an abortion can get one without allowing a “right to choose” up to and including birth.
UK law starts from the perspective that abortion is a crime.
The 1967 Act decriminalises it in certain circumstances, both social and medical and imposed a 24 week limit in most circumstances.
There is an offence of “Child Destruction” where a person causes the death of a child that is capable of being born alive.
UK law therefore does afford the foetus some rights as the pregnancy progresses.
Whether it should or not is a matter of debate, which is why we have Parliament rather than rule by decree.
Most people in the UK seem to support this position, that has (with a bit of modification) been the position since 1967.
As some other posters have said, insisting that there is some absolute right to abortion until birth and that this is beyond debate simply cannot be correct, either as a matter of law, morals or majority opinion.
If you want the law to change to reflect that view, how is that to be done without debate? Also, in advocating a position that many in the UK find extreme, you would also be opening up a forum for those who believe the other extreme (eg the El Salvador option).
The other issue is the biology. A foetus has a central nervous system that is operating from about 13 weeks gestation.
Before that, it can’t feel pain as it isn’t conscious. After that, it can.
That might be an uncomfortable truth, but does that mean it shouldn’t be referenced as part of a reasoned debate?
