In reply to the originating thread post inquiry, the short answer is that such a SCOTUS ruling would default responsibility back upon individual States to determine legality/availability of reproductive choice to it's respective female citizens.
As such, most of the States with the highest rates of unintended pregnancies (which ironically enough retain the highest numbers of opponents to reproductive rights/choices) will impose their "righteous" might and will upon: the most ignorant; the most poor; the most underprivileged; and most ignored segments of a supposed "free" society. Get unintentionally pregnant in California? No problem. Get a 12 year-old pregnant in Mississippi? Fine. Let's defaultingly force the child to get transported to a "legal" State for an abortion, or otherwise bear the due and righteous "punishment" of her pre-adolescent "sinful" transgressions and predilections by means of State-mandated, imposed, and dutifully enforced criminal statute in bringing a pre-teen's unintended/unwanted fertilized embryo to full term and delivery.
[Just today, on CNN, there was a televised effort to reunite an 18-month-old infant with her (currently) 13[!] year-old mother.
Um, hello?
This means that the "mother" in question was no more than 12 years-old, and probably 11[!!!} years-old at the time of her initial pregnancy/delivery. I'll lay 100 to 1 odds that the missing "mother" is herself the progeny of young parents (or single-parent) living in abject and crushing poverty and ignorance, with neither the means nor financial wherewithal to pursue any options (legal or otherwise) to rightfully and (safely) medically terminate such a conspicuously untimely, untoward, and undesirable circumstance.
Is it really a good idea to criminally enforce pubescent teen girls into motherhood at 11 years of age?
Is it really?
Does anyone really think that criminalizing/prohibiting abortion choice will reduce unwanted pregnancies?
SPARE ME any arguments of "legal adoption" alternatives. Unless or until virtually ALL unwanted children are placed (now) within adoptive homes/families (and NO, "foster homes" are NOT adoptive homes), there is NO compelling or persuasive argument to be lent that any and all unwanted embryos MUST be brought to term and delivery by means of enforceable criminal law. Barring passage of specified federal law that specifically prohibits legalized abortions of any kind, anywhere (a law that would NEVER see passage in both houses of Congress); only the poorest, most ignorant, and most vulnerable would be forced to accept unwanted/unintended pregnancies beyond realistic (and legal) recourse, means, or methods.
IF only...the evangelical Christian opponents of reproductive choice would adopt the Beatitudes from Jesus as precedent over the OT's 10 C's...the meek and poor that hunger and thirst for righteousness might one day find the fulfillment, comfort, and mercy that is often spoken of, but all too infrequently lent on their behalf.]
