Since this is the "Words and Wordplay" section, let's be clear. Until it's born, a "baby" is called a "fetus." Nobody is for killing babies (or eating them).
If the question of Pro-Life vs Pro-Choice was as simple as deciding when a fetus becomes a human being, there would be less argument. Some would argue that it's not human until it's viable outside the womb, but medical science has made that a moving target. Ultimately, you can make a good argument for humanity at the moment of conception.
Nobody likes abortion. The complications come when we fail to appreciate that this human fetus is still part of the mother's body. I don't claim to have the answers, but it must lie somewhere in the middle.
The people who say "It's my body and I can choose" do need to be cognizant that it's a human life they're ending. Is it murder or justifiable homicide?
The people who say "All life is sacred, abortion is murder" need to understand that while the fetus is inside the mother, her needs are equally important. There are lots of ways that humans kill each other, only a few are called murder.
My personal feeling is that (as a society) we should take *all necessary steps* to avoid unwanted pregnancies. This includes easy access to contraception and sex education. Abortion should be accessible, but only as a method of last resort. It is, imho, justifiable homicide and therefore to be avoided if at all possible.
