We're all cowboy surfer rednecks that love our guns and religion, are all broke with maxed out credit cards and overweight with a nasty case of diabetes.
So you get a country where service employees working on Christmas is considered totally normal, but fundamentalists crow on and on about the disrespect done to Christianity by deigning to acknowledge Hanukah and Kwanzaa. Which is ironic, because prior to Kwanzaa being invented from whole cloth and Hanukah morphing into Jewsmas, it really was solely and only the Christmas season.
Damned capitalist pigs ;-) (yes, I'm originally American).
Oh, and there are more guns than people in America, but those are mostly concentrated in rural states where guns are easier to obtain legally. The population of America has only recently tipped over from being mostly rural/suburban to mostly urban/suburban.
