Blackwell, former Ohio Secretary of State, debates noted atheist Christopher Hitchens relative to the US being a Christian nation.
Blackwell, who now works for the ultra-right wingnut group, the Family Research Council, didn't have a chance! Probably because he has no clue as to what he's talking about.
If you haven't read the Newsweek story, "The Decline and Fall of Christian America," by editor Jon Meacham, it's worth a look. For one thing, he gives too much attention and credence to R. Albert Mohler, Jr., president of the Southern Baptist Theological Seminary. Mohler, a rabid fundamentalist, represents only one very noise segment of Christianity, and would be shunned by many of the mainstream denominations - their clergy and laity - as an example of ignorance and superstition.
Nevertheless, Meacham makes many interesting observations and from what the most recent polls indicate, the number of people who identify as Christians is dropping, while the numbers for unaffiliated as well as atheists and agnostics is growing.
