Abortion is murder. Millions of lives have been nipped at the bud because the parents didn't feel like being hassled by a kid, and our society gives the OK because "it's a woman's right to decide what happens to her body". Here's the thing...it's not the woman's body. It's the baby's body, and it happens to be growing inside the woman.
I don't know how any sensible person can make the decision to abort their baby, and not hate themselves for it.
My aunt was pregnant two times and gave birth to a still born both times. Now, she can no longer have a baby. Try telling her that a woman should get to decide to abort because it's inconvenient to be pregnant.
As for stem cells, I don't really have an ethical problem with it but I still think that there is a threshhold of science that we should not cross.
