I assume that the parents are proud progressives. As such shouldn’t they have aborted the fetal tissue before it was born. How unprogressive of them to let the defective fetus live. (I am being sarcastic of course.)
The ad was interesting because they really played the religious tone strongly during the description of the disabled daughter, so I was surprised that it turned out to be a pro-libhole. Otherwise, as you sarcastically surmised, that poor little disabled gal — who is the daughter of some libholes — was a prime candidate for an abortion.
