Pro-choice. It doesn't cause harm to anyone. If you think that aborting a baby is wrong, it is. But you aren't aborting a baby, you are getting rid of a small group of cells that haven't even developed into anything yet. You would kill more cells by scratching than having an abortion. If it was a living breathing thing, then I would have a huge problem. But you gotta learn when to draw the line.
Doesn't the potential or the cells going to become human matter? I think it does.
