If you said "an egg," you're wrong. It's a baby chicken.
Seriously. It's a chicken, the moral equivalent of this:
That's Personhood USA's take on the matter, anyway. According to the group, "preborn children" "begin to exist immediately at first contact of the sperm with the oocyte [egg]" and are "created in the image of God."
was made in the image of this:
If the group achieves its goal of changing the legal definition of "personhood" to include fertilized eggs, any birth control method that interferes with the implantation of a fertilized egg in the uterus—including intrauterine devices (IUDs) and some birth control pills—would be outlawed.† All abortions would be banned, even for rape victims. Rebecca Kiessling, who was conceived via rape and is a featured speaker on Personhood Mississippi's "Conceived in Rape" tour (you've got to wonder what kind of T-shirt they came up with for that tour), states, "A baby is not the worst thing that could ever happen to a rape victim—an abortion is."
While I can't speak from first-hand experience, my guess is that rape is a prime contender for "the worst thing that could ever happen to a rape victim."
† Medically, pregnancy is considered to begin when a fertilized egg "implants", or becomes attached to the uterine wall.
