The short answer is, in our society, abortion is enshrined as a human right, and people in general are not mentally trained to think of the preborn conceived entity as a fully human being. That is why people speak of “
expecting a baby”, “when the baby
comes into the world”, “we’re
going to be parents”, and so on. Any attempts to stop individual abortions would plunge us headlong into civil war, and would make the United States into another Bosnia or Afghanistan. Catholics and other pro-life Christians (but especially Catholics) would be stigmatized in the way radical Muslims are now. (Very few Muslims are “radicals”, the vast majority are ordinary people just trying to get by, like everybody else.) And if you’ve noticed, Americans like their lives to be easy, pleasant, peaceful, and for everybody to get along with each other.
I may raise the hackles of the “life begins at conception” folks — and I am convinced that human life from its earliest stages, from the first cell when it begins to divide, must be treated as a person with an immortal soul whose termination would be murder, because
we simply don’t know when that life is ensouled — but to see the preborn conceived entity as a human being, at a very early stage,
takes a certain degree of faith. Zygotes and blastocysts don’t “seem” human, and nobody except Catholics and various pro-life evangelical Christians views them that way — that is why embryonic stem cell therapy is seen as a great medical advance, instead of a Mengele-like experiment. I have to think that, when an unwanted pregnancy becomes known (missed period and pregnancy test), there is an atavistic urge to
“do something right now, waste no time, hurry up and do it before it starts becoming something like a baby”.
I have likened it to a hypothetical society where newborn children could be freely murdered up to a certain point after birth — who wouldn’t recoil from that? — but I recently discovered that
this has been extremely common throughout history. The human race doesn’t have the best track record where the matter of protecting preborn and newly born children is concerned.
The world has historically been a pretty tough place to be born into!
