If a fetus is already aborted, shouldn't we use it in whatever way we can, though? I doubt there are many fetuses that are aborted purely for the purpose of improving stem-cell research. I could be wrong with this, since it is purely an assumption, though. But if the fetuses are aborted anyways, shouldn't we use them? No, because it tries to put some kind of validation on abortion. "It's okay because we harvested the cells". Especially given that there are multiple viable options for harvesting in ways other than embryonic, I see no need to allow embryonic stem cell harvesting.
