Amy (Hall, I believe) left this comment at Stand to Reason's blog to a pro-choice individual who favors keeping partial-birth abortion legal. I found this part especially poignant.
So here's what I would ask you to consider: Rather than say that this kind of procedure is okay because the other kinds are okay, maybe your thinking ought to slide the other way—that is, maybe if the visual of the partial birth abortion procedure bothers you, it's because it says something true about all abortions. And maybe this isn't a distraction but the most important question of all.
Here's the Planned Parenthood Services page which notes they performed 264,943 abortions in 2005. This is up from the 255,015 abortions they performed in 2004 and up quite dramatically from the 165,174 abortions they performed in 1997. They've increased the number of abortions they perform annually by nearly 100,000 in 8 years.
