You don't get to redefine science at will. Abortion is homicide.
I am not redefining science. I gave you a study that was performed by researchers and you rejected it because it did not factor in abortion. You are the one redefining science, based on your theological convictions. You seem to have no clue about the history of infanticide in humans and other animals. And I bet you do not want to know. The concept that killing an infant, never mind a fetus, is a form of homicide is relatively new in the history of mankind.
Granted I do agree that abortion is wrong. Because I respect all life. But you seem unwilling to put our heads together and figure out how we can adjust things for this factor. Do you want to disqualify from the list of peaceful ones all countries that practice abortion?
Also, you have not addressed this:
Do you think that a homosexual union is less likely than a heterosexual union to have an abortion?
