The Planned Parenthood videos reveal how callous the abortion industry is, and how callous we have become for taking it all so lightly. In one of the videos, over a salad and a glass of wine, a Planned Parenthood doctor casually explains how they can sometime preserve body parts of the unborn babies that can be sold. She glibly discusses how they sell the heart, the lungs, and the liver.

My colleague John Rabe made a great point recently about this scandal. Either it will cause a great shift in the national debate on abortion, or it will show us the great searing of the American conscience.

In light of these egregious revelations, here are five questions you can ask to challenge those you know who support abortion:

1. If the unborn babies are not human, then why is there a market for their body parts? Why would anyone want the heart of a “blob of tissue”? Who cares about the lungs of a “POC” (Product of Conception)? How can a mere “blob of tissue” even have a heart or lungs?

Indeed, one thing this scandal does is underscore the humanity of the unborn. Though some try to dehumanize them by calling the unborn fetuses, fetus comes from the Latin foedus, and it means “unborn baby.”

2. Do the mothers undergoing the abortion know what is happening to the remains of their dead babies? In fact, how can one retain the maternal instinct and participate in the deliberate destruction of the unborn in the first place?

As Mother Teresa once asked, “If we accept that a mother can kill even her own child, how can we tell others not to kill one another?”

3. If these aren’t little unborn babies being killed in the Planned Parenthood clinics, then why does someone at the clinic have to reassemble all the parts of the aborted baby after each abortion to make sure nothing is left in the womb that could cause an infection?

Pro-life activist Carol Everett used to work in the abortion industry. She once told me, “In the front counseling room, the young woman is asking, ‘Is it a baby?’ And she’s being told, ‘No.’ But in the back, every single baby, as early as it can be done, has to be put back together—the arms, legs, hands, feet, the head, and the spine—to be sure it’s all there. It is a baby.”

4. How do they avoid the comparisons to what the Nazis did to those human beings whom they devalued and treated as subhuman?

In the book The Rise and Fall of the Third Reich, William Shirer dedicates about a dozen pages to some of the medical experiments the Nazis conducted on human beings, usually Jews, in the concentration camps.

For example, experiments were done on men and women, exposing them to freezing conditions to see how quickly they would die. All the data was carefully timed and recorded. Any objecting medical personnel with bothered consciences were removed from their posts.

5. Why should Planned Parenthood get a lot of their money from taxes? Why should “we the people” be forced to support such a dehumanizing organization?

George Grant, who wrote Grand Illusions on the subject of Planned Parenthood, was not surprised by the scandal. He told me, “the gruesome reality has been Planned Parenthood’s stock-and-trade since the time of its notorious founder, Margaret Sanger.”

Mother Teresa noted, “Abortion is a crime that kills not only the child but the consciences of all involved.”
