How much "common ground" is there?

C-Fam interviewed Rocco Buttiglione to clarify his reported remarks on protecting the unborn child. I found this particular question and answer enlightening:

Q: Is true common ground possible?

A: There is only a limited setting where we pro-lifers and they pro-choicers can unite in a struggle together – that is where the freedom of choice of the woman is crushed, as well as the life of the child. I don’t think we need to give true pro-choicers any bribe to convince them to join the struggle with us. If it is true, as they claim, that they are not for abortion but rather for freedom of choice, then this gives them the chance to join with us to prove it.

If they don't, then they really are not pro-choice, but pro-abortion. They like abortion. They don’t think that human life must be supported, but one must reduce the world's population by any means necessary.

Also, this initiative forces people to make up their minds. Up until now, the label 'pro-choice' could be a cover for a national socialist ideology of lifeboat ethics: Because there are too many people on earth, all means are acceptable to reduce population. We see that in third world countries, abortion has been much more cruel and widespread than in Western nations.

So now we shall see if common ground is possible.
