Prove it.<quoted text>
World War 2
As I said back then more people believed in God percentage wise
Lots of Americans believe in 'A' god - it's not necessarily yours - and it's always been that way. That was pretty much the point, even when the country was founded.
Christians, for the most part, refuse to believe that these days.
Much more comfortable to claim this is a Christian nation, than to accept that it isn't, and never has been.
