A professor at Purdue University says pro-life advocates should not display images of what abortion does to babies because those comprise child pornography.

While arguing in favor of abortion at an event hosted by a campus pro-life club and the College Republicans, David Sanders, an associate professor of biology at Purdue, said images of aborted babies are child porn because they are photos of a naked, dead child, Campus Reform’s Anthony Gockowski reports.

“What would you call the public display of a butt-naked body of a child?” Sanders asked. “I would call it child pornography. Do they have their permission? Do they have the permission of the fetus? Obviously not.”

He went on to question whether his opponent, a pro-life advocate from the organization Created Equal, should be showing these images.

“Do they obtain permission of the parents to show these images of children?” he asked about Created Equal, a pro-life organization whose members sometimes publicly display images of unborn babies, both intact and alive and aborted and dead. “Naked children. Dead, naked children.”

“So it’s a child?” one audience member asks.

“So you admit it’s a child!” another says.

You can watch the whole thing here, Sanders’s remarks about images of aborted babies being the equivalent of child pornography are at the 38-minute mark.
