Not irrelevant at all, since you could arguably say a cow has the level of consciousness and ability to perceive pain as the infant, and yet, it's what's for dinner.
But without going there...
Then we'll just put the infant under total anesthesia first. There. No more moral problems.
No moral problems, if you have no moral problems with offing an adult person under anaesthesia.
Again, irrelevant strawman. Once the fetus has gained the status of personhood... their humanity is not revokable via temporary measure.
Anyway, I'll state in a more formal manner my argument, so that we're not wasting time trying to poke holes with fallacies.
I believe that the value of humanity, of our difference from other creatures that share our world, is our mind. It is what gives value to humanity.
I believe (with reason, logic and evidence) that the mind is something that develops during the gestational period, and not immediately following fertilization.
Ergo, I assign humanity to the fetus that has developed a mind.
In practical terms, I err on safety; I'll give berth to fetuses that have developed the necessary structures for the formation of mind.
Without humanity, a collection of cells with human genetic material is just that. It isn't anymore, it isn't any less.
As a result, I wouldn't want to impose on the humanity of another person, reducing their rights, for the sake of the collection of cells. The humanity of the person that currently exists, outweighs the potential for humanity of blastose.
