I have tried.
Four facts.
The baby is a human person. DNA proves that. (Science!)
The baby is a separate person from the mother. DNA proves this. (Science!)
The baby is alive. (Science!)
Killing a person because they are inconvenient is wrong. (universal civilized social conviction)
Do you know what they come back with?
"But does it have a soul?"
I respond that I am not talking metaphysics but objective reality. And in objective reality it is wrong to kill a human baby.
"Yeah, but does it have a soul?"
Every. Single. Time.
Even the atheists who maintain that none of us have souls.
-——Do you know what they come back with?——
“It’s the mother’s right to choose”
The rights of the mother are superior ti those of an unborn child
That is their argument
