It may simply be an indicator that the brutal suppression of apostasy is illegal in those countries. If people have other options for social networking beyond religion, and they don't have to fear for their own safety or livelihood when abandoning their parents' religion, there isn't a whole lot that any particular religion offers that can't be obtained more cheaply from other sources. I'd expect that those who have a real need for religion will likely gravitate towards smaller cults that are more specifically tailored to their preferences. Perhaps those who would prefer to believe in aliens than in angels will become something like the Raelians, and those who prefer fairies and pixies will join an aseembly of neo-animists. No doubt the Jedi Order, Pastafarianism, Discordianism, Subgeniusism, Order of Stendarr, Cult of Cthulhu, and similar pseudo-religions will continue to enjoy the affiliation of people who want their "religion" to be fun, and somewhat ha-ha-only-serious. I think the fears over "Muslim invasion" are largely unfounded. The high religious adherence and over-median birth rate will probably attenuate within one or two generations, as the children and grandchildren of immigrants embrace liberal democracy and assimilate to their new country's native traditions. This will likely manifest earliest as homosexuals outing themselves and abandoning their parents' enclaves. A large number of people only declare a religion because of discrimination by the religious against the non-religious. Once declared non-religion becomes a significant minority, there is much less incentive to pretend. Like the article said, only the most strongly committed will remain. And then they will die off.
