Since you do not hold this position, I take it that we are just talking about this academically, and that is fine. But just so that we don’t get hung up on semantics, let me clarify one point.You ask me to defend a position I don’t actually hold, so it is quite uncomfortable, but here it goes: One could say that a person is a human being that has become separate from his mother. It is a somewhat arbitrary distinction, but there are many distinctions in science that are somewhat arbitrary. So it is coherent and well-defined. Words can be defined any way we want as long as we agree on the definitions. It is what we say about those words after they are defined that really counts.
There are two kinds of definitions: a nominal definition and a real definition. A nominal definition defines a word; it states what the word means. A real definition defines a thing; it states what the nature of the thing is.
It is true that nominal definitions are arbitrary. You can make words mean whatever you want them to mean. For example, if by the word “heaven” I mean hell, and by the word “hell” I mean heaven, then I can most definitely say that all devils are in heaven and all saints are in hell - and I am quite consistent. (Of course, you should never use words with unconventional meaning like that without telling your listeners first; otherwise, they will be shocked.)
However, real definitions are never arbitrary. When we are asked to judge what that zygote is that is in the womb of a female human being, we are being asked to state what is the nature of that thing. And we answer that it is a human being and that it has a right to life.
Now, usually the word “person” is used to designate a human being that is the subject of rights. (Lawyers sometimes use the word “person” also to designate any entity - an individual man or a corporation - that is the subject of legal rights, but this is not the meaning I have here.) In that sense, even the zygote is a person because it is the subject of human rights.
However, if you now arbitrarily define the word “person” differently, and say that the word “person” designates a human being that has become separate from its mother, then of course the zygote is not a “person” (because it is not yet separate from its mother). But, to be perfectly consistent we will deny the proposition that the zygote has no rights just because it is not a “person.” For you can arbitrarily change the meaning of words, but you cannot arbitrarily change the nature of things. If the zygote by nature has a right to life, then it has a right to life regardless whether you nominally define it a “person” or not.
