Note that some have such view for religious reasons, some have such view for
purely scientific ones (e.g., for a fetus in a stage late enough that it would have survived in nICU if delivered prematurely, it
's hard to make an argument that merely
being attached to a placenta and not to nICU life support somehow turns the fetus from a live
human being to «perfectly fine to surgically excise
part of mother
's body».
