I do think it is a baby. But I also think that a woman has the right to do whatever she wants with her own body, and the fetus is still a part of the body.
One of the MAIN reasons I support legalized abortions is because of illegal abortions. Lots of women die all around the world because of back alley, illegal abortions. Also I can't possibly know what a woman is thinking or going though when she is pregnant and cant take care of the baby.
I read a very good book called " the cider house rules" (quite different from the movie) and it was about a doctor in Main that ran an orphanage/abortion clinic in the early 1900s. There were so many horror stories about alcoholic women giving birth to deformed babies, and rape victims killing themselves, and women dying from getting coat hangers shoved up inside them.
So, I just do not judge, and realize that I might not know everything about everything.
If I know a person that is going to have an abortion, I will try as hard as I can to talk her out of it, but will always support her decision to abort.
