As much as you might be right, I would find it distasteful to use a child who has just gone through such a traumatic experience to score political points.
Anyone who thinks it's acceptable for any rape victim to be forced to carry their rapist's child, can take the longest walk off the shortest pier they can find, then keep walking after that.
I don't give a good goddamn fuck about their opinions.
A significant amount of republicans probably sincerely believe that this tragedy is worth "saving the lives of all the other babies that would have been murdered."
Their moral calculus is foolish and predicated on questionable-at-best axioms. They are well meaning but functionally bad people.
Another significant chunk also adheres to "the cruelty is the point." They are bad people.
Unfortunately, for various reasons, republicans have a disproportionate amount of power in the US.
Aaaaand now they've shunned her and are insisting the baby is Satan's spawn because the girl was a harlot for choosing to be raped. According to Deuteronomy, this mother and child are worthy of death. Hallelujah!
My conservative U.S. House rep insists that a good conservative man cannot be expected to resist a 12 year old girl. That's just science, y'all!
