Before we can answer this question, we must first answer three others:
1. What is abortion?
2. What is a fetus?
3. What is wrong?
There are essentially two types of surgical abortion procedures: the Suction Curettage procedure used in earlier abortions, and the Dilation and Evacuation (D&E) procedure used in later abortions.
Suction Curettage
This is sworn testimony by abortion doctor Martin Haskell describing the Suction Curettage procedure:
When we do a suction curettage abortion, you know, roughly one of three things is going to happen during the abortion. One would be that the catheter as it approaches the fetus, you know, tears it and kills it at that instant inside the uterus. The second would be that the fetus is small enough and the catheter is large enough that the fetus passes through the catheter and either dies in transit as it’s passing through the catheter or dies in the suction bottle after it’s actually all the way out.
Dilation and Evacuation
This is sworn testimony by Dr. Haskell describing the Dilation and Evacuation procedure:
Let's just say…we left the leg in the uterus just to dismember it. Well, we'd probably have to dismember it at several different levels because we don't have firm control over it, so we would attack the lower part of the lower extremity first, remove, you know, possibly a foot, then the lower leg at the knee and then finally we get to the hip. And typically when the abortion procedure is started we typically know that the fetus is still alive because either we can feel it move as we're making our initial grasps or if we're using some ultrasound visualization when we actually see a heartbeat as we're starting the procedure. It's not unusual at the start of D&E procedures that a limb is acquired first…prior to anything having been done that would have caused the fetal demise.
When you're doing a dismemberment D&E, usually the last part to be removed is the skull itself and it's floating free inside the uterine cavity…So it's rather like a ping-pong ball floating around and the surgeon is using his forceps to reach up to try to grasp something that's freely floating around…So typically there's several misdirections, misattempts to grasp. Finally…the skull is brought out in fragments rather than as a unified piece.
This is an excerpt from the medical textbook
Abortion Practice by abortion doctor Warren Hern:
The procedure changes significantly at 21 weeks because the fetal tissues become much more cohesive and difficult to dismember. This problem is accentuated by the fact that the fetal pelvis may be as much as 5cm in width. The calvaria [head] is no longer the principal problem; it can be collapsed. Other structures, such as the pelvis, present more difficulty…A long curved Mayo scissors may be necessary to decapitate and dismember the fetus.
This is an excerpt from an interview with Dr. Haskell in
Cincinnati Medicine:
D&E's, the procedure typically used for later abortions, have always been somewhat problematic because of the toughness and development of the fetal tissues.… I just kept doing D&E's because that was what I was comfortable with, up until 24 weeks. But they were very tough. Sometimes it was a 45-minute operation.
In summary, abortion is a procedure to "decapitate and dismember the fetus."
What is a Fetus?
Consider the differences between a human fetus and a human infant:
All of the differences between these two can be summarized as follows:
• Difference in size
• Difference in level of development
• Difference in degree of dependency
A human fetus can move, suck her thumb, sleep, dream, fight with her twin, enjoy music, and feel the pain of an abortion.
Now consider the differences between a human infant and Barrack Obama:
The differences between a human infant and Barack Obama are far greater in degree than the differences between a human fetus and a human infant. However, all of the differences can still be summarized as follows:
• Difference in size
• Difference in level of development
• Difference in degree of dependency
In short, a human fetus and a human infant differ only in those ways in which any human at any stage of development differs from any other human at a different stage of life.
What is Wrong?
Is it wrong to kill a human infant? After all, a strong case can be made for infanticide:
1. Abortion costs money, and many poor people do not have the money to spare on abortion, especially in developing countries. Infanticide, on the other hand, is absolutely free. The procedure requires no doctor’s consultation, no medication, and no follow up visit. It requires no special equipment and can be performed with any number of common household items, such as a kitchen knife or even a shoestring.

2. Criminalizing infanticide is dangerous for women. In societies where infanticide is illegal, young women who do not want their child, but who have neglected to have an abortion, are forced to secretly dispose of their babies in back alleys or public restrooms. Giving birth alone, without any medical care, is extremely dangerous, especially in such unsanitary environments. When legal, however, infanticide is 100% safe. There are absolutely no health risks associated with the procedure.
3. Women have the right to choose. To rob a woman of her infanticide rights is to rob her of her reproductive freedom. Don’t like infanticide? Then don’t do it!
4. Infanticide prevents unwanted children. For example, some mothers do not know that their child is physically or mentally handicapped until after the child has been born. It is a great injustice that these mothers are now forced by the state to raise a child they do not want.
5. Infanticide is ultimately better for children. Unwanted children are much more likely to experience abuse or neglect; infanticide ensures that every child is a wanted child.

6. Infanticide benefits society. In developing countries, particularly those affected by the Aids epidemic, orphanages are overcrowded and the streets are swarming with homeless children. Countless millions are expended every year to keep these children alive, when the money could be used much more effectively to build economies and create jobs. Infanticide, administered systematically on a large scale, would relieve societies of this burden, thus creating a better world for all.
7. Criminalizing infanticide violates the separation of church and state. Those who oppose infanticide rights do so because they believe it is evil to kill children, but this assertion cannot be proven empirically by the scientific method. Thus it is merely a personal opinion based on religious beliefs, and as such, it cannot form the basis of public policy in a secular democracy.
So do you really believe that infanticide should be illegal? Why?
