Greenland left the EU, so why not Ireland?

The European Court of Human Rights has ruled that Ireland's constitutional ban on abortion violates a pregnant woman's right to receive proper medical care in life-threatening cases. The reason for the ban may have been to appease the country's Catholic majority but if Ireland wants to stay in the European Union, they need to follow the EU's rules. Ireland has resisted extending abortion rights to women whose pregnancies represent a potentially fatal threat to their own health despite a 1992 judgment from the Irish Supreme Court that said Ireland should provide abortions in cases where a woman's life is endangered - including, controversially, by her own threats to commit suicide. In fact, those huckaleros in the Dail seriously need to consider some massive reforms because apparently, the abortion doctor and the patient can both be charged with murder if the abortion was deemed not medically necessary. That is stupid because personhood isn't achieved until you've left your mother's uterus, and unborn foetuses don't count as people and therefore cannot be murdered.
