Catholics are "pro birth" in general, but it really doesn't have much in scripture to support it; there is of course the "Quiverfull" movement which aims for each birth to be "an arrow in the quiver of God's army"
So for all of that, it's clearly a religious viewpoint and that raises serious 1A questions.
A question I've never seen addressed by those who hew to this belief system:
Apparently roughly 1 in 4 pregnancies end in miscarriage, which is (using the belief system above), God is performing an abortion. How does that reconcile with that stance.
My personal take is simple: "every baby should be a wanted baby"
The politics of it started half a century ago, and the politicizing of abortion was very much intentional:

It's important to have discussions based on logic and facts, rather than emotion. It will be interesting to see how that plays out here.
