Well I despise all religions and find them all actively toxic at bottom, which a case like this sort of demonstrates (what a f**ing pointless waste of a life).
HOWEVER the idea of forcing any kind of medical treatment on anyone against their wishes is not a very comfortable one. And the argument that she should have accepted treatment against her principles for the sake of her babies is not very comfortable either: women in general are far more reproached than men are for doing risky things when they have children, to say they should not be allowed to take risks or indeed choose to die is not thatfar from saying that women's lives should be regulated and controlled because they are baby-producers not autonymous human beings.
And the bottom line (lines?) is that the Sun is quite happy to have a pop at a minority superstition when equally gruesome things are done in the name of other superstitions and, for instance, shitloads of airtime is given to the opinions of celibate old men on what women should be permitted to do with their bodies on the grounds of superstition.
And there is existing medical technology which can save JW patients in the event of haemorrhages, which appears to have not been used in this case, perhaps through human error. ANd, really, it's perfectly possible that the woman in question would have died even if she had been given an actual blood transfusion: it happens (and we don;t know the full medical details of her particular case).
This one is extra upsetting because (it appears) that the patient was unconscious when the decision had to be taken as to how to treat her, and though she had signed a form, it's reasonable to assume that she hadn;t actually really expected to need a transfusion - it's not that common after all, not a standard part of childbirth.
ANd FWIW were I a surgeon in charge of these kind of cases, or someone with the power of making medical legislation, I would insist that when any patient has to sign a consent form about something where superstitious and cultural scruples may be involved, that the patient, wherever possible, signs the form in a private consultation with the medical professional, which remains confidential (unless the relevant emergency occurs). THis might perhaps save a few lives of people who have paid lipservice to their family or partner;s superstitions but actually don't fancy risking death for them.
