You area the one using language improperly .. and making fallacious arguments. Just because the sperm may go on to become a human .. does not make a sperm a human. You are conflating and confusing what might exist in the future - with what exists in the present.
Obviously. But what surprises me is your lack of vision. When does a fertilized egg stop being a human being? Or perhaps you like to view things in retrospect? Is an old man human? Is a young man human? Is a boy human? Is a young boy human? Is a baby boy human? Is a baby in utero human?
Or better yet, if a man loses an arm is he still human? If Joe looses a leg in battle is Joe still a man? Does Joe cease to be human if he is missing a part of his body? How much of his body can Joe lose before he ceases to be "Joe the human being?" It's the age old question of "esse" What is Joe's essential nature? What makes you think that Joe, the fertilized egg isn't Joe?
Why is it not a woman's right to choose. The onus is not on the woman to justify taking ownership of her own bodily function away - the onus is on you to justify taking these rights away ..
A woman doesn't take ownership of her body. What a strange thing to say. When a woman stubs her toe, she says, "Ouch" I stubbed my toe! She doesn't say, "I hurt my
body." No, she says, "I hurt
myself". A woman's body is part of her essential being that distinguishes her from other people.
She doesn't take
ownership of her body as if she bought it at Macy's. No, she takes
responsibility for her body because that is her nature as a creature God made. Consider a flu shot. If a woman gets a flu shot, she allows the doctor or the nurse to inject her with stuff that isn't part of her body. The body metabolizes the ingredients, keeps what is needed and eliminates the rest.
Sperm is injected into a woman during the process of procreation. The sperm is not part of her body; it comes from a male. The woman contributes an egg, which is hers and the male contributes sperm, which is his. How does a zygote form? Who the hell really knows, but one thing is certain. The zygote isn't essential to the woman or the man. In essence, it is something or someone completely different. What they call that? It is called the embryonic development of a human being: i.e. one of the
many stages of human development.
But science is so dehumanizing isn't it? So sterile. So mechanical. What you call a zygote is a human being in development and that is the essential nature of our existence. Unlike God who never changes, human beings are in a constant process of change over time. Why do discussion of abortion use Latin based words? Because abortion is a medical procedure designed to end a human life in order to cover up another human quality, the lie two people told each other with their bodies.
You are wandering way off the Utilitarian abyss - and this is a very dark path you don't want to go down .. Utilitarian Justification for Law - unless of course you really despise essential liberty.
I believe men and women lie with their bodies and make promises they don't intend to keep. I believe the law intends to protect innocent third parties.
