I figured it would be worth mentioning what a "Partial Birth" abortion involves....

"According to the American Medical Association, this procedure has four main elements.[8] First, the cervix is dilated. Second, the fetus is positioned for a footling breech. Third, the fetus is extracted except for the head. Fourth, brain of the fetus is evacuated so that a dead but otherwise intact fetus is delivered via the vagina."

So basically, a live fetus (or baby) is pulled from the host (mother) where its brain is evacuated (surgeon cracks open a living beings head with scissors and sucks out their brains).

D&X sounds very clinical and can mask what is actually happing so this diagram might help visualize the procedure.
