The topic on abortion can be quite a heated discussion. Both sides attempt to justify their own positions, often providing analogies and rhetorical statements to try and sway the crowd. However, believe it or not, it is not the anti-abortionists (i.e. those who are pro life) who are to try and justify their position. Those who are pro choice and supporters of abortion are the ones that are supposed to try and justify abortion, as abortion is not natural, it is generally a selfish act and does not benefit the human race.
It's my body
I would say the most common argument given in support of abortion is: "It's my body, i can do whatever i want with it." This is fundamentally flawed on many levels and it begs the question. If the embryo was truly that person's body, however, then the last thing they should want is to have their body sucked into a tube that tears your body apart, let alone someone using tweezers to rip their body apart limb from limb. Indeed, if it were their body, they would reconsider the thought. The burden of proof is on the one claiming that the embryo is the mother's (or carrier's) body.
At this point you are probably thinking, "No, you have it all wrong! We do not mean that the embryo is her body, but that she has every right to do whatever she wants with her body, of which the embryo is in." However, that makes less sense than what i have suggested, for the embryo is obviously separate from the carrier—damaging the embryo does not affect the carrier in any way. Therefore, while you may argue that they have every right to do whatever they want to their body, in order for you to remain consistent, you would have to admit that the embryo is to be left untouched, as the embryo is not her body. It is more logical to assume that the embryo is considered by the pro-choice arguer the carrier's body.
But speaking of carriers, we can—in other ways—show how claiming that the embryo is the carrier's body is absurd. Say there is a woman who cannot conceive and asks her friend if she can be the carrier. Her friend accepts and after conceiving decides to have an abortion; her reason being that it is her body and she can do whatever she wants with it. The parents will obviously have something to say about this.
Also, to support such a position is to accept and support the implications. One of those implications is scenarios like, "Don't worry if i get pregnant, i can always abort." In other words, abortion is the new birth-control pill. Due to the fact that abortion is practically done at the convenience of the carrier, i'm sure there are more scenarios like that one. It is not unheard of to hear that the child will merely be wasting the mother's "resources"—which implies that the child is obviously a burden.
Cells die all the time, why care about an embryo?
This appears to be another rhetorical statement made to support abortion. However, the questioner is falsely comparing the two, as cells dying would be a natural process and the abortion i am talking about is an unnatural, intended act. If the abortion occurred naturally, then i have nothing against it.
Controlling overpopulation
One argument, though i would say a very sad one at that, that may appear in support of abortion would be using abortion as a method to control overpopulation. Of course, this runs along the same lines as using abortion as the next birth control pill. To use abortion as a method to try and "solve" overpopulation is absurd and does not strike the root of the problem. The problem isn't that there a lot of births occurring world-wide every year, the problem is lack of self control. In a society that promotes sexual interactions through the media and other forms of communication, you can only expect many to burn with passion every now and then—apparently more often than desired.
Even worse is that some just do it for fun and other foolish reasons. Rather than promoting a mindset that says, "Abort the child! It will only be a burden to you," we should be promoting a mindset of purity and higher standards concerning relationships. The benefit will not come from constant abortions; better is through the promotion of high standards—which do not degrade the human race.
