Describing preborn children as parasites is downright despicable! But that is exactly what a professor at the University of California in San Diego was caught doing by a pro-life student who took a picture of slide presentation (see above) and sent it to a friend, who then posted the picture on Twitter.
The slide explained the supposed parallels betweens fetuses and cancers and stated: "The fetus: a legitimate parasite: rapidly grows, invades, manipulates immunity of mother, reshapes blood vessels."
