Well, no it’s not that simple, because right away, with “innocent child”, you are embroiled in semantics. Why not say, “anyone who advocates destroying human embryos is a murderer”? Presumably, this is what you mean. Why would you hesitate to pronounce this judgment, then?
You are the one playing with words and I won't play. Abortion is murder. Argue with yourself.
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.
