Well said. Yes, I've seen many such threads here.
I often get the impression that the general belief of “the right,” as illustrated by the FR sample, is that both abortion and childbirth are “really” wrong, while fornication and adultery are only “technically” wrong. (It’s just a piece of paper, after all.)
In my opinion, this makes it unlikely that “the right” as a political movement is going to generate many productive ideas to reduce either abortion or out-of-wedlock child-bearing. If you love the cause but bemoan the outcome, you’re going nowhere.
