What does Amnesty International stand for?

Ryan Anderson, in The Weekly Standard, has a piece criticizing Amnesty International's new policy with respect to abortion rights.  Here's a bit:

But even people who differ on these issues can see why Amnesty International's advocacy of abortion is a mistake. It severely weakens its ability to form broad coalitions of human-rights defenders. It makes Amnesty International indistinguishable from all the other standard-issue leftist organizations that cluster around international affairs. Worst of all, it will have disastrous consequences for relations with religious believers--especially Catholics--who will be forced to distance themselves from the organization's other work.

In fact, the Church has already responded. Soon after I publicized the new abortion policy on the First Things website, the news reached the Vatican's Pontifical Council for Justice and Peace. In an interview with the National Catholic Register, the Council's president, Renato Cardinal Martino, said that "individuals and Catholic organizations must withdraw their support," since "by pushing for the decriminalization of abortion as part of their platform, Amnesty International has disqualified itself as a defender of human rights."
