I think it is great that you would never have an abortion. However, being pro-choice to me is like saying that that people can have a choice as to whether or not they can kill someone (who has been born). Yet it is illegal, because people should not do so simply because it is obvious that it is wrong.
I'm not trying to hassle you when I say this, in fact I'm not trying to hassle you about anything. But I personally know many people who have brain disabilities, leg disabilities, and much more. They are some of the happiest people I know. In some ways I wish I was like them. They love the fact that they were born. They help me realize that sometimes I just need to stop and smell the roses. They may not be the smartest, but they are happy with what they have, as all of us should be.
Even after a baby is born, though, she still needs her mother's milk to support her life. We still need nutrients even when we are all grown up to keep us alive. It's no different than having to be in the mother's womb to survive.
So what you're saying is that we change from cells into humans right as we are born? Are human bodies not made up of cells til death?
