There are many, many dimensions to the abortion issue, but for me, it reduces to one simple question.

From the pro-life perspective, abortion is a case of a mother paying a doctor to murder her child. However, most state anti-abortion laws, even in relatively conservative states, punish the doctor who performs the abortion, but not the mother who pays for it.

This is the equivalent of prosecuting the hitman but letting the one who plots and pays for the murder go free. The reason why the states are doing this (even conservative states like South Dakota) is a no-brainer: most of the moderate pro-life constituency would melt away if the mother were held criminally liable for the so-called murder.

If you don't believe me, watch this video of pro-life activists when confronted with the question of what to to the mothers.

Either abortion is murder or it isn't. If it's murder, then every anti-abortion voter must reconcile the concept of what to do (legally) to the mothers.
