If you believe in Jesus as the son of god (I don't) and you believe there is a god (I'm agnostic) and you somehow believe that God chooses who lives and who dies (as right wing religious  people do), then you must, from an intellectual and logical standpoint, support the right to have an abortion.  Here's why.

If you believe God decides when a person is born, then if a woman has an abortion, then it was God's choice and God's will that this fetus not eventually be born.  If you believe God decides when a person lives or dies and you believe a fetus to be a person, then God chooses to have that fetus die in the womb.

Oh, and if anyone wants to disagree with me, I can just claim that God says so and find some bible passage (My bible of course) to back me up.
