A necessary response

Abortion is a spontaneous natural response to about 50% of all successful inseminations before or shortly after implantation. The effort to impose legal restrictions on a natural process is basically dishonest, as are all proposals to affect a result by targeting the wrong cause.
Why promise something that cannot be accomplished by law? You’ll have to ask the legislators that. Maybe because it’s easier than actually providing for the general welfare?

Reproduction is a risky business. Not only is the initial failure rate 50%, but maternal deaths from pregnancy contiue to rise in the U.S. “In 2016, as many as 900 women between the ages of 16 and 43 died from pregnancy- and childbirth-related causes.” And that likely does not include women who die from opportunistic cancers that seemingly take off after some pregnancies. In any event, naturally hazardous experiences should not be coerced, regardless of the high falutin’ moral intent.
