Bearing in mind that not all conceptions result in a pregnancy because they mostly don’t manage to implant into the uterine wall, how do you feel about the fact that conception happens well over a week before implantation?
It is estimated that 50% of all conceived human beings fail to implant. When pregnancy begins remains a matter of opinion. Most obstetricians and gynecologists say it starts at conception, others contend that it begins at implantation. Either way, a new human comes into being (human being) when the male and female haploid gametes (sperm and ova) fuse in the Fallopian tube, producing a diploid gamete (zygote). This new human being travels down the Fallopian tube and into the uterus, where they seek implantation, growing all along the way. Remember, the mother of this child does not know they exist during this stage. It takes between 7-10 days for this new person to make their journey and begin to implant, spurring the production of Human Chorionic Gonadotropin (hCG), the hormone detected by pregnancy tests.
Now that we have established the facts, I’ll address your question. You seem to be alluding to the pro-abortion argument that claims that since half of all human beings fail to implant into the endometrium, killing another 25% through induced abortion should elicit little to no concern. Here’s where that ‘argument’ falls apart. Notice I used the term induced abortion. Induced means that a living human being was intentionally targeted for destruction — for death. The other form of abortion is known as spontaneous abortion, or miscarriage. It is wholly unintentional. In other words, no human being was intentionally targeted for death.
Let’s take this idea beyond the womb. Imagine a mother swimming with her toddler. She is carefully holding her child as they kick their legs and learn to swim. Now imagine if this mother, wanting to end her responsibility to care for this child, suddenly pushes them underwater and drowns them. This is the equivalent of induced abortion. Now imagine if this mother, blissfully embracing her role as a parent, slips and loses her grip on her child and they drown. This is analogous to spontaneous abortion. Accidental drowning is the leading cause of death for American children between 1-4 years old, killing almost 300 each year. Should this fact mean that the intentional drowning of a child should elicit little to no concern?
Bottom line: Intentionally killing an innocent human being is wrong, regardless of their location or what stage of life they happen to be passing through.
