Most non-americans seem very suprised when they experience first hand the level of some of the religious "fervor" exhibited, especially in the "bible belt". I'm an east-coaster, but I'm still subjected to daily threats of hell and damnation as advertised on at least three large signs on my way to work.
And the money thing - yes. We seem overly concerned with spending more time (as a nation) than any other nation in getting it. Maybe it's because we can't afford simple health care?
Regarding your signs, I find it interesting how much religion seems to need to frighten the shit out of people to gain converts but still maintain that god is love.
I was appaled when I saw a documentary on Phelps and his family shouting abuse at a funeral, among other things, telling a family that their sun was burning in hell. I regard what he has done to his children as abuse, by moulding them to his sick worldview.
