I'm interested to know how pro-choice supporters view "ending human life" as opposed to "killing the unborn." As you've noticed and pointed out, terminology is law. Because something is legal that makes it right. Because something is illegal that makes it wrong. Because you call something that it is not, it makes it ok. It's not a baby, it's a cluster of cells, or a zygote, or a fetus. Therefore it's ok to kill it because it's not actually alive yet. My argument is that it's a human life, and an innocent one at that. Full of potential. Is it ok to end an innocent human life? Once sperm joins egg and DNA replicates, 2 cells become 4, then 4 become 8. That process happens independent of the mother's body, yes it is nourished and supported by the mother, but the process is independent. That to me makes an individual human life. In this light, the abortion argument becomes harder to support.
Just my thoughts, have a good one friend.
