Shredded up? Source? And no, that video of them "selling baby parts" is not a source, it was faked.
Dismembered. Vacuumed. Who cares? Babies are many times not killed and removed as an intact humanoid. I don't know what you mean by source though if it's related to that or religion. I just said it isn't much of a religious issue because the Bible and the Quran don't exactly talk about abortions.
I don't see a problem with killing babies
See, when you haven't been born yet, you aren't exactly "sentient" and you don't really know what's happening around you. If you kill it, the baby doesn't experience any pain. Now take for example killing a bunch of 13 year olds who know exactly what's happening
"A baby in the womb apparently feels no pain. Suddenly, when it is born, its nerves suddenly activate therefore enabling pain."
^Is this what you mean? If not, when do you think that a baby's development stage suddenly allows for pain?
