Well... here's an example of badly missing the concept (from a New York Times article, "Soldier Sues Army, Saying His Atheism Led to Threats.")
"When Specialist Jeremy Hall held a meeting last July for atheists and freethinkers at Camp Speicher in Iraq, he was excited, he said, to see an officer attending.
But minutes into the talk, the officer, Maj. Freddy J. Welborn, began to berate Specialist Hall and another soldier about atheism, Specialist Hall wrote in a sworn statement. “People like you are not holding up the Constitution and are going against what the founding fathers, who were Christians, wanted for America!” Major Welborn said, according to the statement.
Major Welborn told the soldiers he might bar them from re-enlistment and bring charges against them, according to the statement."***
Having said that, I would bet there are a lot more places in the world where you would actually be punished for professing Christianity than there are where Christians do the punishing (though, the later type of story is more newsworthy.) An example of the former.
Thanks David for the NYT link!
