Viability isn’t 15 weeks. It’s 24 weeks. Google it. It’s exactly where Roe v Wade established it, that’s not changed and it likely won’t as viability has something to do with organ development, particularly the lungs. The only way to lessen that time is develop an artificial womb. We’re not there yet. There’s been some success with mice, but other mammals like him are trickier.
This overturn of Roe is based on another Big Lie from fundamentalist groups. People have been convinced that women are having abortions as a means of birth control and that fetuses are practically ready for the world at outlandishly earlier and earlier gestation times. Neither or which is true.
Google images of human fetus at 15 weeks and look for one’s labeled as for miscarriage day (not 15 weeks early, which is 24 weeks or viability) and see if you think there’s any way those fetuses could have survived.
There is no “driving down the age of viability”. It’s gone as low as it can go without a artificial womb. Most premies (that premature) have life long disabilities too. You should Google that a well. They don’t have a good quality of life. It’s immeasurably cruel to force some babies to be born.
