I prefer, in all but technical-medical discussions, to use the more common words (newborn vs neonate, mother vs female parental unit, whatever) because the common terms more accurately connote membership in my family, the human family.
Hence, child rather than embryo.
Anyone who uses the term “rhetorical flourish”, is the person who is using rhetorical flourish.
Some try to impress others with their vocabulary, even when it means moving away from the subject at hand. I’ve learned to ignore them and even better, not even acknowledge their existence.
They are as bad, if not worse than the grammar or spelling police on this forum.
