so does a pig, yet we enjoy bacon without guilt. rudimentary consciousness and the ability to feel pain is not enough. we don't murder newly borns because we see the potential human beings they can turn out to be. the same things goes for fetuses.

Could you please explain in more detail your criterion for potentiality as it relates to human beinghood? Judging just from what you have said in this thread, both of the following implications flow from your criterion of potentiality, correct?
(1) The fetus is a potential human being.
(2) It is not the case that the mereological sum of a sperm cell and unfertilized ovum is a potential human being, even though the zygote is a potential human being.
Both of those sound strange to me. The fetus at issue here is not a potential human being; the fetus is a human being. And, prima facie for consistency, if something like the zygote at conception (or what results from it after a couple rounds of mitosis, if you are not simply joking about your 4-cell stipulation) is a potential human being, then the mereological sum described above is as well. So this all just seems bizarre to me.
Further, I am totally confused on another issue. Suppose for a second you were right in claiming that the fetus is a potential human being. How does that help your position? Did you miss the memo that potential Xs do not have the same standing as Xs? For instance, potential persons do not have rights. Persons -- not potential persons -- are what have rights.
By the way, the discussion also seems confused to me because you appear to use 'human being' as proxy for 'person'. This will probably lead to notional confusion, since it is relatively common to take human beinghood simply to have to do with the descriptive question of whether or not something is a member of
Homo sapiens sapiens; whereas, on the other hand, moral personhood deals with the question of rights. Obviously, we will be talking past each other, since I will readily agree with you that the human fetus at early gestational age is a human being (oh wait, your position denies that it is a human being, since your position holds that it is merely a potential human being 🙄 ), but I will still readily disagree with you that it has rights.
