The left ignores science about abortion since a DNA test prove beyond a shadow of a doubt that the mother and preborn child are separate, individual human beings.
Liberals have done weird mental gymnastics to "prove" that human embryos are in fact not human life. It basically defies belief and science.
What they should admit, as does Camille Paglia, that abortion is barbaric. Paglia is pro-abortion, but she doesn't try to make demonstrably false statements as to whether human embryos are human life or not.
