I stumbled on an article explaining the increasing irreligious climate of America, sometimes seen to be the last stand of societal Christianity in the West. Could it be that America will follow Europe in things religious? Its definitely a cause for concern.
"America's fastest growing religious allegiance is "None"."
Nevertheless, we should be suspicious of any attempts to predict widespread atheism. The secularization hypothesis of a few decades ago failed spectacularly in its predictions, and similar fates may await predictions of the same sort today.
