There is no rational, scientific basis for calling a group of developing cells a human life until it is capable of living outside of its mother. If it's not a human being, it's not murder. Any restriction on the mother's right to terminate a pregnancy before that point is nothing more than a "christian" version of Sharia law.
If it's against your beliefs to have an abortion, then don't have one. But you don't have the right to force others to live by your superstitions.
When they talk about restricting abortions, Republicans lose all credibility on standing for "freedom".
If I wasn't technically challenged, I'd find and post the picture I've seen online of a (aprox) 16 week old fetus in a doctors(?) hand. Maybe someone else can do that for me.
In that picture, it sure looks a lot more like a baby than "a group of...cells)!
