But remember, the pro-aborts are the folks with the shifting lines in the shifting sands.
Pro-aborts confuse the road map with the real world...they are the ones drawing imaginary lines at so many differing levels of gestation. They are the ones who are trying feverishly to find imaginary reasons to defend their "right" to kill.
This is a real world...and fetuses are real people. Words don't change reality. Reality is, no matter who vainly tries to argue it out of existence.
The pro-aborts' attempts to "determine" the moment of "humanity/personhood" doesn't alter the reality that the fetus is a separate human being, identifiable as one, from the moment of conception.
The fetus may depend on someone or something else for life's necessities, but so do most of us.
That position is indefensible, hence their need to "legalize" the killing ignoring the immorality of it.

You seem to be so focussed on their imaginary moments, that you don't recognize your own. It is a metaphysical mistake to say that there is an instant or moment where conception takes place. The completion any particular process (e.g. DNA strands joining together) can't take place instantaneously because the individual atoms making up the DNA are interacting with non-DNA atoms and are already starting their post-completion processes.
The other mistake is defining murder to be anytime after the "moment". If you do decide to do that, the legal sanctions for such "murder" should be trivial since there are no sanctions for killing an egg before that "moment".
In short having a significant legal step-function at a moment that cannot exist is not a defensible position.
