If your concern is in fact to improve matters in Ireland, rather than pontificating on Mumsnet, emotive pleading to remember Savita is not going to help.
(a) Savita's death was primarily caused by medical negligence, and this will be repeated at every stage by the pro-life lobby. Her death was highly politicised by the initial reporting - with the consent of her husband, and thus morally correct to do so, but there is no doubt it was politicised. Maternal death rates in the uk and Ireland are quite similar, between 8 and 10 per 100,000 births respectively (depending on who's counting), so it is difficult to listen to British posters lamenting how dangerous it is to be a pregnant woman in Ireland. Sepsis, which killed Savita, is the biggest cause of maternal deaths in the UK. Of all those poor women, Savita's name is the only one I know.
(b) Savita's death probably was contributed to by the lack of clarity in the law, and the way this was being interpreted by a conservative and unsatisfactory culture in Galway. However, subsequent legislation has purported to clarify matters, so again it will be argued that no change to the Constitution is necessary.
There are better examples of the current inhumanity of Ireland's law - the poor asylum seeker who was forced to give birth at 24 weeks, rather than being allowed an early and safe abortion, being one. Of course, the simple fact is that Ryanair, and previously ferries, have allowed Ireland to have a ban on abortion without faving the consequences in all but a small amount of cases, and that is a moral hypocrisy in itself.
Still, yesterday and today is no time to be churlish. Two seperate issues.
