There are two very different groups of the so-called Pro-lifers -- there are true Pro-lifers. But the other group of those who call themselves Pro-life are really anti-abortion people.
Most of the Pro-lifers are really anti-abortion, including nearly all of the American Catholic prelates. 
That is what this article is trying to say. What we have to do is to always make this distinction in order to pierce thru their shell of falsehoods with a much more accurate truth. 
BY calling themselves Pro-life the Catholic bishops are 'hiding' behind a protective misdirection falsehood. The Repubs are doing the same. Another point is that this is much more about money and power than it is about Pro-life. They pound their message home, we do not. We do not endlessly repeat our messages of their being really about ONLY anti-abortion and money and power.
And about the 'common good' the Right and the Religious Right are not at all about that!!!
