I think we should definatly have the choice but I also worry about things that could go wrong, it might be a morbid way of thinking but childbirth is a complicated thing and many woman have died doing it.
I'm not sure whether the choice to give birth 'unassisted' should be given, by that I mean alone and outside of any medical care as suggested in the interview. One of the reasons I'd be against that level of free will is the control families can have over a mother to be, especially where it involves deeply held religious beliefs. Realistically an 18 yr old who's entire support network (family) tell her she is better off alone and will be in agony if assisted is pretty powerful. I know that would be rare but bearing in mind emergancy care orders still have to be obtained in the UK when bllod transfusions for a child or adolescent are refused on religious grounds AND that there are adults who elect to die rather than recieve blood.
The influence over an 18 yr old might be greater because as the years chalk up more independance is gained but that's not to say older mum's would be immune to brainwashing and unlike refusing a life saving blood transfusion in this case there's a little person involved with no say in the matter!
I'm 100% pro choice but within reason and I would be very worried if a movement like this caught on over here along with the suggestion that having no medical help available was a reasonable decision to make.
It's a world away from a home birth (which I think are ace, but am just chicken to do it as a first time at 36!!).
