How exactly is this sculpture pro-life?

Not that I have any problem with the sculpture and its depiction of Britney Spears giving birth. In fact I wish i could find a picture of the sculpture showing the head exiting the vagina. But alas, these were the best I could find. Wanna guess who helped sculptor, Daniel Edwards? How bout his kids, age 3, 6, and 8. What a wonderful family pastime. "Hey dad, how do you like that pussy now?"
