This will be about abortion, if you don't like topics like this then don't read on.
I don't think anyone ever wants to kill babies, unless you are a sick fuck. So let's decide that the debate over abortion is really a debate about at what point an embryo or fetus becomes a life.
For some, it is when a childs head comes out of it's mother. This allows for abortion up to almost nine months. Then can induces labour, breech it, deliver all but the head and then kill the baby. Probably by making a hole in the back of it head and sucking out it's brains.
For others it is as soon as the sperm is in the egg. These people can't use the pill because one of the pills jobs it to prevent the embyo from attaching to the uterus walls, which could be construed as killing the baby.
