Just as Christianity at some point will defeat Christianism. From a National Geographic article on Indonesia:
[A]lthough Indonesians continue to embrace Islam in their private lives with greater fervor, it's become clear that most don't want religion to be enforced in the political sphere. "So many people equate Muslim piety with radicalism," says Sidney Jones, an Indonesia specialist with the nonprofit International Crisis Group who has lived in the country for more than 30 years. "Indonesia is full of examples of why that notion is wrong." As Islamist politicians have moved to regulate women's dress codes and ban activities like yoga, moderates have begun to make their voices heard. In the Indonesian parliamentary elections this past April, candidates backed by Muslim organizations received less than 23 percent of the vote, down from 38 percent in 2004.
