I agree with some other posters. God’s Word doesn’t change. I think his message would have been more compelling if, instead of sounding pro abortion, he could have just stopped with the militant stance, and done something like counsel women who feel guilty years after an abortion.
I can see a tactical re-evaluation: that happens all the time as people weigh alternative paths to the same goal. And he must know that: his bio shows a lifetime of involvement with all kinds of issues which have legitimately utilized all kinds of approaches.
But to outright say that there is a private right to kill your child before it's born? That really cuts the child out of the human race. And in doing so, it decisively undermines the whole idea of "Life" being one of those inalienable rights --- for anybody --- which hurts us all.
