Understanding that this poll is as unscientific as you can get, one of the findings, at least for Christians, should be a little surprising. Of the 144 scenarios that lead to the American apocalypse, both Christianity and Militant Islam made the list.
the surprise? Christianity was voted as more likely to cause the end of America than Militant Islam. Christianity ranked 35th while Militant Islam ranked 52nd. At first glance, this seems unlikely to me, but it gets even more unlikely when you read Slate's given reason for why Christianity may ultimately undermine the United States.
Just as, per Edward Gibbon, the rise of religion killed Rome's fighting spirit, increasing spirituality turns America into a nation of pacifists. We get attacked and don't fight back.
So, here's to hoping that Christianity leads to the end of America.
