Me: "If killing an adult human is immoral, killing an embryo is immoral. They are both human, in different stages of development."
muleskinner: "See 321. SO you would agree we must not kill any sperm, as well."
No. Sperm has 1/2 the human chromosones. It cannot grow into a human being itself. It is part of a human, but it is not human.
At conception the 23 chromosones of sperm join with the 23 of the egg and a human life starts.
Why do you think the stage of development affects the species? Or the morality of killing a human?
See, Pro-Life people have to stick to this argument no matter how illogical it is.
An embryo is not a human life, but if they admit to that then the abortion debate is a non-issue for the first 8 weeks of pregnancy. Pro-lifers and the church won't have any of that, so they stick to this ridiculous notion that it is a living human being the MOMENT the sperm and egg join.
