Genesis, unfortunately you have misidentified my stance. I did not claim that determining personhood is fallacious and pointless; rather that basing a pro-choice stance on personhood being conferred at birth is such. This is because pro-choice is still a perfectly valid stance to take
even if personhood were granted at conception instead. While personhood is a useful and interesting debate, it actually doesn't relate.
How can personhood be granted to a biomass and yet abortion still be a valid option? Let me, for the third time, provide this link:

If we grant that even at conception a fetus has a right to life, that right to life does not negate an individual's right of self determination. JJ Thomson, in that article, uses the analogy of waking up one morning and finding that you have been hooked up to a world famous violinist. His kidneys have failed and he is hooked up to you so that your kidneys can keep you both alive. This is not a permanent situation, it will only last nine months. Does the violinist's right to life mean that you have no choice in this matter? If you disconnect yourself, the violinist will die. While it can be agreed that it would be a very fine and noble thing if you decided to suffer through the next nine months, can you be legally required to?
Or let us take this a step further. The violinist isn't connected to you, but rather just needs to take one of your kidneys. Without it he will die, but this time you only need to undergo the discomfort of your kidneys being removed. Can you be forced, by law, to surrender your kidney? The violinist still has the right to life, but does that right to life come with a right to use your body as is necessary to support that right to life?
And let us take it even a step further. The violinist doesn't need your kidney, just your blood. It will be a fairly painless procedure, of minimal inconvenience to you. Without an infusion of your blood, the violinist will die. Can you be legally required to donate your blood against your will? Again, it is a very fine thing to do if you are willing to give your blood to him, but can you be so legally required?
Now let us consider this from a different perspective entirely; the violinist is starving and needs food. You have food. Can you be legally required to give the violinist your food? Again, without the food he will die, and again he has a right to life, but does his right to life trump your own rights? And again, we can say that it is a fine thing to do to give up what you have to help another creature live, but on what grounds can we say that this much be required, that the right of life of one individual conquers the rights of another individual?
Perhaps you now see why your objections don't apply? I am not claiming that abortion is acceptable because a biomass is not a person, rather I am claiming that abortion can be acceptable
even if the biomass is a person. That is why I find the discussion of personhood pointless and fallacious; it is a variable that does not affect the outcome. It is sort of like debating if a "theater" provides a more cultured experience than a "theatre."
Defining personhood is indeed a cakewalk. A zygote is a person! Poof, I have done it with ease, and yet the above remains. Being a person does not give the fetus the rights to the mother's body.
If that was murder, then any time a late-term fetus is aborted, they could call it murder.
Not at all, under your own perceptions, that would be closer to manslaughter than murder (and even that isn't quite correct). After all, it is not like the abortion doctors out there are plotting, with a sinister twist of their handlebar mustache, how to kill fetuses ("feti"?). While I would still object to manslaughter, at least I can understand a perspective that would so label abortion. But labeling it murder? No, that has no basis and must be rejected by any sane, reasonable anti-abortionist.
Many couples, however, have to wait for years to adopt because abortion has drastically reduced the number of children available for adoption.
I will admit that I have no personal experience in this, but having talked to a good number of individuals who have adopted, the wait has to do with the adoption process and not the supply of children up for adoption. Indeed, this is confirmed by the children in the system currently. If it were a problem with supply, then there would never be a child in the foster care system for more than a month.
