There certainly is shrill and misleading rhetoric on both margins here, but even your article admits that viability was at "23 or 24 weeks" in 1992 (or was it 1993).
So, 10 years ago, viability was 2 weeks more than in Santorum's example.  I hope that is not some sort of implied assertion that medical science hasn't moved viability up since 1992, is it?
I mean, because your author is the one bringing up the study from way back when, right?
And then there is the 14% survival rate at whatever week he admitted to.  I'm not going to fight over what survival rate is appropriate, just as I can't do anything but cry with great sadness at the plight of the Schiavo family -- including the husband.
But, I find it reasonable that people would shed tears at taking away a 14% chance at life.
One thing that hasn't been brought up in this round.  I remember reading that the great majority of PBAs were committed by just a few doctors in a few places, like Minnesota or South Dakota.  Seriously, by "few doctors", I mean like 6 or 7.
Hundreds or thousands of other abortion doctors would argue that they had never found a good reason to perform even one PBA, but these guys would do like 125 per year.  Or am I imagining this?
If it is just 6 or 7, then fuck them and the horse they rode in on.  Americans have spent 7000 lifetimes arguing over this issue so these jagoffs can... whatever whatever.
