Explains to some measure why the left is so heavily in favor of abortions, even during live births. Doesn't this professor as well the students who wholeheartedly accept his ideas as gospel recognize that they, too, were once 'parasites' to their biological mothers?

An instructor claimed unborn babies are ‘parasites.’ This professor says no way.

A California professor recently compared unborn human babies to “parasites” during a class presentation—and one instructor, who has extensively studied parasites, is pushing back against that claim, calling it “bad science” and “borderline satanic.”

Late last month Pascal Gagneux, a professor at the University of California, San Diego, made headlines after an in-class slideshow claimed that unborn human beings are “legitimate parasites” with distinct parallels to cancerous growths.

Gagneux is a professor specializing in evolutionary biology, primatology and glycobiology, according to the school’s website. Following a major media response to his slideshow, Gagneux complained that his presentation had been featured on “right wing ‘pro-life’ media,” and he wrote an email to his students assuring them that his “point was not to indoctrinate you with the notion that fetuses are cancers.”
