There are at least two kinds of right-wing nonsense related to medically necessary abortions:
1. Claiming abortion “is never necessary to save the woman’s life.” They are simply ignorant as to all the ways a pregnancy can go wrong in a life-threatening way. Shocking, but there’s no requirement that Righties pay a moment’s thought to medical expertise before passing laws that affect the practice of medicine. And SCOTUS, who knows better than your average state legislator in Idaho, is happy to go derelict in its duty and look the other way.
2. Slightly less unhinged, but equally dangerous, are those who play this semantic game where they re-define medically necessary abortions as something other than an abortion. So that they can maintain their “total opposition to abortion,” I guess. But if they don’t fix the laws to clearly allow doctors to do their jobs, it amounts to the same thing. An uncertain legal regime that will force doctors to stand by while a woman lays there dying.
