Abortion is murder. Period. Calling it "abortion acceptance" is just a way to make it sound more PC. Maybe we should rename a serial killer's murders to "murder acceptance" or "extremely late term abortion."
Would that make it any less than murder?
Murder is a legal term. It means illegal homicide. Since abortion is legal it cannot be murder.
Ah, but it is murder. Try kicking a pregnant woman in the stomach and see if the courts don't charge you for murder.
We can also see that when women are pregnant they say, "I'm pregnant with my baby!" They don't say, "I'm pregnant with a hunk of cells that means nothing right now"
One of the reasons behind Roe vs Wade was that the law never saw it that way at that time.
