IN MY OPINION the reason this is so is because in all cases the head of the religions are men. Although in the Catholic Church I do believe that if the mother's life as well as the child's life are in danger an abortion can be done without danger of excommunication.
In a number of non-Christian religions the women have no rights, the men have all the rights. He can divorce the wife and take the children etc. So why would men be interested in changing women's rights. They get everything now, they aren't going to give that up. Again JUST MY OPINION and a generalization of what I've heard.
