I can’t help but think of the situation in the movie A Sinful Life, where a lab worker is trapped in the sperm bank during an L.A. Earthquake, surrounded by broken vials and a sea of white. 9 months later the birth certificate says, “for father, see list”. 
I’m one of the few people who’s truly neutral on the issue of abortion, and here’s why:
If a fetus is a human being, then an abortion would be killing, and abortion ought to be illegal for all people unless the parent’s life is in danger. Furthermore, women who do abort should be tried for abortion (worse than manslaughter, better than 2nd degree murder), and doctors should be tried for performing an illegal and harmful medical procedure.
On the other hand, if a fetus is not a human being, then abortion should not be illegal, for anyone. Abortion clinics should be safe places full of education about all the various alternatives (adoption, abortion, raising the kid) and about pregnancy, and abortion clinic bombing should be seen as a horrible deed.
However, as a 15 year old single male, I do not feel qualified to judge whether a fetus is a child or not. Furthermore, I feel that there is not enough information out there for me to properly judge, and that there is no reason to look at this information until either: there’s a direct vote on it, or I have a girlfriend/wife who is pregnant and abortion is a possibility. I am perfectly willing to leave this decision to the two groups who are more qualified: medical professionals, and people (women) who were pregnant at some time. The problem, of course, is that these groups are not monolithic coalitions, and that I have no idea which are more trustworthy, etc., which is why I’m still neutral.
However, I harbor no quarter for people for people who want to outlaw abortion “except in cases of rape and incest”. Such people are saying a fetus is a child except for icky sex. Why? Why is an icky sex fetus any less of a baby? These people are either ignorant (of why they hold that position), in which case they should be educated strongly, or they believe in outlawing abortion for other reasons (i.e. punishing the woman, growing the population), in which case they are stuck in the 18th century, and ought not to be engaged.
