Here's where it gets interesting. Shahid makes the case that religious conviction in America is being replaced by political conviction.
From 1937 to 1998, church membership remained relatively constant, hovering at about 70 percent. Then something happened. Over the past two decades, that number has dropped to less than 50 percent, the sharpest recorded decline in American history. Meanwhile, the “nones”—atheists, agnostics, and those claiming no religion—have grown rapidly and today represent a quarter of the population.
But if secularists hoped that declining religiosity would make for more rational politics, drained of faith’s inflaming passions, they are likely disappointed. As Christianity’s hold, in particular, has weakened, ideological intensity and fragmentation have risen. American faith, it turns out, is as fervent as ever; it’s just that what was once religious belief has now been channeled into political belief. Political debates over what America is supposed to mean have taken on the character of theological disputations. This is what religion without religion looks like.Source: The Atlantic.
