What Phizzy said is basically about right, even in the US, (at least on either coast, maybe not the Midwest or deep south, as much).
Religious people have been in the minority for quite some time, and for the most part, the particularly religious are considered misfits. Many claim a religion, but pretty much interpret their "religion" they way they want to, and this has been this way at least as long as I have been around, (since the '70s). It is likely that fewer people today "identify" with a religion, because they have a greater degree of honesty about it.
Despite how the USA may appear to the rest of the world, most people are not religious fanatics by any stretch. The main issue here is the minority on the religious right have a disproportionately large voice in our political system, due to the way our state representation works. When this is fueled by a plutocracy that preys on the uneducated for its own gain, you have what you see from abroad looking at the USA. (Obviously, this should be its own thread, didn't mean to hijack).
