You not.
But in both situations it is human
In nearly all cases an invitation was given
Who actually argues that a zygote or fetus is not human? Like legitimately?
No one actually argues that any abortion gets rid of a Fox from a women’s womb. I mean have you seen that?
In matters of biology, a blastocyst, zygote or fetus is at best a potential human. Because biology doesn’t treat such specimens the same as fully fledged humans or indeed even children. Biology doesn’t care. Such specimens could die or they could be aborted through actual medical adivice given by actual trained doctors. Abortion is considered a legitimate medical intervention after all. Just consult your local OBGYN. You know? Someone who is actually knowledgeable about fetal development in depth. (And fyi even they don’t refer to fetuses as “children.” Such a term is biologically inaccurate, fun fact. Biologically speaking we have terms like “fetus” for a reason.)
Doctors will always give priority to the pregnant person in medical situations. Why do you think that’s the case dude?
Short answer, biologists actually disagree with your assessment. Maybe don’t invoke them?
