I guess the next question is whether or not the right to life supersedes the right to control one's body, especially when the life in question is dependent fully on the host's body. Maybe if technology were to advance more to the point where the embryo can be removed and developed outside the woman's body, the argument over abortion would cease to exist.
But then, would the question move to who would be responsible for the care and cost of the child, seeing how entitlements are not a popular topic to discuss...
It's all relative. For every argument that abortion is a device for convenience, there are the same number of arguments that a woman should have the choice to choose what she wants for her body.
