I am not pro-life, though if my mother had had the benefits of a sonogram and abortion laws in 1965--she might have seen my cleft palate--and it might have been over for me. So I have some sympathy for those who believe that the fetus is a living thing.
After all, when a woman WANTS her child, she doesn't refer to the contents of her womb as "the fetus" but as "the baby". Certainly if babies were being killed after being born we'd all be up in arms--not that I'm saying that's the case with abortion,but you might be a bit more broad-minded...or are you only allowed to be broad minded if you're a liberal?
The good people at Notre Dame have as much right to object (non-violently) to Obama speaking there as anyone has to cheer him. I approve of civil disobedience on the right as well as the left, as well as the protest of a peaceful petition. Rock on, Cardinal Newman Society!
