I'm not sure why the anti-abortion crowd would be thrilled, unless this is an indicator of decreasing numbers of single moms. Oh and of course one must also ask "why is marriage (as opposed to committed life partners, or some other arrangement) important, and how is "married" determined?"
I think the bible is a lot more prescriptive when it comes to abortion than sex outside of marriage, but I'm not exactly a scholar and that's far from the only reason for taking a stance on the issue
Your points are all valid, but I do think there's a component of fixed meaning that projects itself in relation to multiple perspectives and agendas
That said, I couldn't tell if the number was increasing or decreasing with a glance at the underlying data cited
I'm assuming it's an increase because it seems kind of high and correlated statistics like marriage rates have to my knowledge also been decreasing in recent decades
I'm further assuming that's probably a bad thing because positive outcomes are generally correlated with multiple parents and higher family incomes
But if non-traditional family arrangements are supplanting married families then who knows
The word abortion appears zero times. As https://pubmed.ncbi.nlm.nih.gov/12178933/ points out, the clearest reference is to miscarriage. And there the fetus is valued at far less than a human life.
Just because a religion has taken a position on a topic doesn't mean that their religious texts agree.
Again, assuming it's an increase based on other correlated variables, they're getting what they asked for, so they must be happy, right?
