The Supreme Court cannot determine scientific facts. In 1857 they upheld that a black human was only 3/5 of a human person. Did that make it a scientific fact? NO! In 1973 they determined that pre-born humans were not full human persons. Does that make it a scientific fact? NO! A human person is a human person no matter the color of skin or stage of development and that my friends IS a scientific fact. Abortion kills human persons!
