Do children need religion to grow into good people? Sixty-five percent of Americans think so. And even though younger adults have been leaving traditional faiths in droves, about 48% of them still hold this view. The result is a lot of conflicted parents. While they don't necessarily miss going to church, synagogue or mosque, they do worry that without some sort of religious education, their kids might not grow into morally upstanding people. So while many leave formal religion behind in their 20s and 30s, they slowly, and often somewhat reluctantly, begin to return when they have kids.
