Abortion advocate David Boonin is more honest than some in his movement.

In his book “A Defense of Abortion,” the professor of philosophy at the University of Colorado at Boulder admitted the reality of his position as he looked at an ultrasound photo of his unborn son.

Boonin wrote in the introduction:

In the top drawer of my desk, I keep [a picture of my son]. This picture was taken on September 7, 1993, 24 weeks before he was born. The sonogram image is murky, but it reveals clear enough a small head tilted back slightly, and an arm raised up and bent, with the hand pointing back toward the face and the thumb extended out toward the mouth. There is no doubt in my mind that this picture, too, shows [my son] at a very early stage in his physical development. And there is no question that the position I defend in this book entails that it would have been morally permissible to end his life at this point.

Pro-life writer Sarah Terzo pointed out how Boonin’s honest, yet disturbing position shows a “shocking disregard” for the life of his own son. Terzo wrote:

It is remarkable that Boonin could write an entire book defending something that he concedes could’ve taken the life of his own child. Somehow, the ultrasound picture of his own baby doesn’t sway him. Instead, he defends putting to death babies at the same age as his child in the picture. He shows a shocking disregard for life as he accepts that someone could have chosen to end the life of his son — and he is perfectly ok with that. Boonin’s position clearly shows the moral bankruptcy of the pro-choice stand. The belief that life is expendable and can be destroyed for another person’s convenience is the crux of the pro-choice position, whether pro-choice activists admit it or not. Like nothing else, reading this kind of admission helps pro-lifers realize we are truly standing against an evil ideology.

Boonin acknowledged in his book that unborn babies are human beings when he wrote: “Perhaps the most straightforward relation between you and me on the one hand and every human fetus on the other is this: All are living members of the same species, Homo sapiens. A human fetus after all is simply a human being at a very early stage in his or her development.”

At 24 weeks, his son would have been viable outside the womb. Babies at that stage have all of their organs in place. They can react to music, feel pain and probably even dream.

Yet, Boonin supports killing them anyway in an argument that would allow even his unborn son to be killed. As Terzo wrote, Boonin’s honesty sheds light on the brutal reality of abortion — a reality that has changed many people’s minds about the value of every human life.
