Many leaving churches because of link to politics
As recently as 1990, all but 7 percent of Americans claimed a religious affiliation, a figure that had held constant for decades. Today, 17 percent of Americans say they have no religion, and these new "nones" are very heavily concentrated among Americans who have come of age since 1990. Between 25 percent and 30 percent of twentysomethings today say they have no religious affiliation - roughly four times higher than in any previous generation. Ref. Source 7
