because Indonesia is, apparently, not that "religious"

From Joseph Bottum's blurb in First Things...

In Indonesia, Catholics, Muslims, Protestants, Buddhists and Hindus joined together to protest the liberalizing of Indonesia’s abortion laws...It seems extraordinary that, in an overwhelmingly religious country dominated by Muslims, an attempt to legalize abortion would have gotten even this far. But the interreligious coalition opposing it serves as one more counterexample to the canard that pro-life advocacy is necessarily sectarian—or even monotheistic.

Bottum seems surprised here, but he's probably conflating self-identified religious beliefs or a cultural version of any given religion.
