The source you’re citing appears to be making the opposite point: that 24 weeks is the viability threshold. Other sources (like this one: https://healthcare.utah.edu/womenshealth/pregnancy-birth/preterm-birth/when-is-it-safe-to-deliver) say it’s more like 40-50%, and talk about how when babies DO survive birth at 24 weeks or earlier, it’s often with extreme and life-threatening defects.

If what concerns you is the question of viability, I suggest you look here: https://healthcare.utah.edu/womenshealth/pregnancy-birth/preterm-birth/when-is-it-safe-to-deliver abortions in the third trimester are incredibly rare,(1% of the total) and when they do occur it’s often due to medical necessity. This makes sense when you think about it: why would a woman go through the genuine effort of six months of pregnancy only to change her mind frivolously in the home stretch? Indeed, it’s those medically necessary abortions, which more moderate pro-lifers may deem acceptable, that are most endangered by focus on the supposed murder of nearly-at-term fetuses.

I respect that many pro-lifers come from a place of love, even though I disagree with their conclusions. But there is also a strong element of the pro-life movement that is less concerned about love and more concerned about control of women’s bodies, and reducing their role in society to that of child-bearing alone. The latter is adept at misusing fringe examples as a way to pull at the heart strings of the former, to the point of unreason. I hope you belong to that former group, and you come to see that true compassion includes the mothers and women whose lives are changed irrevocably by pregnancy, and who are best-positioned to choose for themselves what’s right.
