A person doesn't need a name to be human, made in the image of God, and innocent, unworthy of death.
a history,
Their history, so far, is that they were conceived in their mother's womb, and that they are alive to God, and have grown to the point they're at. You want to destroy that.

would that make any difference at all in your likelihood of tolerating his ejection from the plane?
Your argument has nothing to stand on. No one should be killed simply because you don't consider them to be of any value. That makes you a murderer a heart, and you need to repent!
2) if someone left live sperm on your steering wheel
1) Don't be vulgar.
2) Sperm cells are just that, sperm cells. They're not genetically unique beings made in the image of God.
