They believe that this is a "christian" country founded on "christian" principles, which it is not. In fact, the Constitution expressly prohibits the advancement of one religion over another by the government, Federal or State. I would have to say we are a nation of Free Choice.
From Salon and MSNBC:
Is the U.S. a Christian nation?
There's been quite a bit of discussion about Newsweek's latest cover story, "The Decline and Fall of Christian America," plenty of it coming from Christians who are, as you might imagine, unhappy that Newsweek would publish an article saying this.
So far, the most interesting thing to come out of all this is a debate on MSNBC's "Hardball" between writer and noted atheist Christopher Hitchens and former Ohio Secretary of State Ken Blackwell, who's now with a Christian right group, the Family Research Center. It's definitely a lopsided debate -- even if Blackwell's case was airtight, he'd stand little chance against Hitchens, who's well-versed on the subject and is very, very good at discussing it. But it's worth watching anyway.
