makes even more sense than usual

You're talking about the all-or-nothing, absolute rule, zero-sum game gang, here. The concept of nuance is so far removed from the conservative headspace, it may as well be science fiction.

I think their idea here is that 12 year olds should be in school instead of sneaking around getting abortions. Which makes sense if you don't care about context or lack basic humanity

No. No abortion makes sense to them (except their own wives') when they use it as justification to remove agency and bodily autonomy from women.

Most 12 year olds would risk death to give birth, so yes, most people would agree that both on the grounds that it's a raped child and on the grounds that the pregnancy could be fatal to the mother.

Maybe where they live a 12 year old girl can be expected to drive? So getting to a medical center two hours away is easy and convenient? and the nearest medical center is 2 hours away

No, what you missed is that these people are all pedophiles, and part of their weird Christian nationalism is that they hate women having agency, so they need to be impregnating them before that happens.

It's implied in their text that the 12-year old girl is the child of leftists and because of that is already sexually active. Since the left is sex positive that obviously means they're teaching their kids to be deviants by a very young age. Obviously daughter of proper right wing Christian Americans would never do that because she blah, blah, blah.

Maybe it's meant to be extra edgy? This isn't the tone you use when you try to convince people who aren't already on your side.

At this point, I think a decent chunk of them are pedophiles with breeding fetishes who get off on the idea of impregnating children.
