Both are a point of faith. It is a religious tenet that at the moment of conception a "Soul" enters. Prove it. Of course you cant. It's an article of faith.
You can say the same thing about the Resurrection, for goodness' sake. You can dismiss the Resurrection as an article of faith, but if that's all it is, then our faith is worthless. That is not a valid argument.
It either is, or it is not.
I think it's a very hard sell to call a Zygote a "Baby" and then from there call a Woman a murderer and then from there say Abortion is the same thing as the European Holocaust. It sounds irrational.
The bit about the mother is a red herring which I will address below, for I have said nothing about what the mother is or is not. So bear with me.
Whereas, full human dignity and personhood exists in a fetus (says the Church), and
Whereas, 53+ million human persons have been killed as a result of abortion, and
Whereas, a "holocaust" is (among other things) a legal killing of many people,
Therefore, the unrighteous slaughter of innocents can rightly be called a "holocaust."
Three points and a conclusion. That is not irrationality.
Now, to the red herring: The Church says she is a murderer (as per the canons). Now, we do not run her out of society or persecute her for it, because no woman gets an abortion because she is a bloodthirsty maniac. But let's not mince words and obfuscate the fact of the matter. The Church offers healing for her, but that does not change the reality of the situation. That is lacking discernment.
Many people dont believe there is such a thing as a soul. Many others totally misunderstand what a soul is or it's nature and even fewer have a Catholic or Orthodox understanding.
So? Truth and reality are not subject to popular referendum.
People are smart enough to see that a recently divided cell is not the same type of Person as your Grandma. She can bake a fine apple pie. A zygote cant.
Humanity is not defined by the person's value or contributions to society. It is defined by bearing the image of God, and an embryo bears the image of God because Christ once was an embryo.
These sorts of extreme characterizations, outlandish comparisons and ghastly pictures is what is bothering me. You are asking people to adopt certain key elements of your argument based purely on your own personal religious faith. I suggest making the argument against Abortion on different terms and on more solid ground. Otherwise, you will continue to see abortions continue at a high rate.
Then it's already lost. If people are free to define for themselves what humanity is, then why not kill an infant after birth? The Australian bioethicist Peter Singer says, "killing a newborn baby is never equivalent to killing a person, that is, a being who wants to go on living."
So why not abort a 3-month-old infant when the parents find it too difficult to care for it?
Or a two-year-old? They are not really self-aware, not in the way adults are. Kill 'em if they're inconvenient.
There are already people who support those views. Not many, but at one time most people did not support sucking babies' brains out, either.
John Adams was right. Freedom is only suitable for a moral and religious people. When that goes out the window, people either need to be herded like cattle or they start killing each other. It is demonic and I am quite disturbed to see an Orthodox Christian arguing along the lines you are.
My question still stands:
Was Christ fully Man on March 25 as He was on December 25, or was He not?
All the rest is philosophy and personal opinion. But if the God-Man existed on March 25, then humanity is bestowed at conception and abortion at any stage is necessarily murder.
