Not until the end of the century, if then.
Not anytime soon.
Religious people, tend to have higher fertility rates and thus while there might be some secular kids, the majority will stay religious.
True, and regardless of what the young folks here think many so called "atheist" teens will turn back to their religious roots once they start having children of their own, it's pretty much a given.
Even if the 'godlessness' of my generation is overplayed, each succeeding generation generally turn out less religious than their predecessors, however. I see no reason to think why mine will somehow buck this trend.
