It isn't murder is the first trimester, It's choice. You can spin this any way you wish and as Marisa said, obsfucate the point with emotional points but that will not change the fact the it is and will continue to be, the right of the female whether she wishes to carry the fetus or not. You don't get a vote in this.
Try to subtract out the emotion all you wish - make excuses involving the relative level of development - rage against the atrocity of rape/defects, etc. - cite what is enacted in law until you have no more large-font left in you...
None of that changes the negative circumstances surrounding abortion. And I am not even talking from a religious viewpoint - never have, never will. Here's all I've got:
1. Most animals of Earth go to battle over their young, or face danger in order to even reproduce - even in the face of ridiculous odds - because they understand that their youth are more important than themselves.
2. From a non-religious standpoint especially, there is no higher purpose in life than procreation. I challenge anyone to counter this.
3. From the exact point of conception, there is the potential for the being forming from that point forward to become fully developed.
4. Who cares if it acts as a parasite to the mother during the beginning stages of development? Honestly? Who gives a crap at all? There's a disease - A DISEASE - by which the mother's body doesn't stop in its immune system attacks against the fetus and can, therefore, destroy it. If every woman's body reacted this way to pregnancy there would not be much of a human race to speak of. A developing baby IS NOT A PARASITE, end of story. No reason to harp on this, or even mention it. It is completely inconsequential information.
5. Should we really discount the emotional toll having an abortion takes on many women who go that route? Why do you think that happens? Because it is just another "choice" to be made? Oh wait though... too emotional... I guess that means it has no bearing on anything at all, by your account. I would say it is due to an innate, even if manifesting only as a subconscious understanding of points 1-3 above.
All of the above, and
I STILL believe it should be the woman's choice. I just understand that it is a heavy price for which there is no true payment, and should never, ever be taken lightly. And the subject should never, in my opinion, be relegated to the realm of cold-facts and law alone. It is a travesty to even attempt to do so.
