First, the callousness of some of the PP workers shouldn't come as a surprise. People that do horrible things for a living tend to become inured to their work - it losses its horrors over time. (Talk to anyone that works in an ER if you don't believe me.)
Also, working as an abortionist is a natural profession for a sociopath or sadist. Surgeon is one of the top five professions for sociopaths, at least according to some sources. And abortion is essentially a type of surgery. Look to that Philadelphia abortionist from a couple of years back for a trenchant example of what I'm talking about.
Second, I have a question. For people that are pro-abortion rights, why do you think selling an aborted fetus is a bad thing? After all, having decided to terminate the pregnancy, what difference does it make if the fetus is sold for a profit? There's much offense being taken at accusations that PP has done exactly this, but why? You already think the fetus doesn't have any rights as a human being, so what difference does it make if one sells them for whatever reason afterwards?
I can understand why some women having abortions might not want to do that (cases of abortion to protect the health of the mother & cases of extreme congenital defects spring to mind immediately), but why is it considered a bad thing otherwise? The positions seem completely at odds to me.
