Godless? Christian? What?

I've always had a problem when people say that we need to put G'd into our public life. Given the diversity of our population, are we talking about the G'd of the Hebrew Bible, the G'd of the Christian Testament, The G'd of the Koran, or the Multifaceted Hindu G'd? The fact is that any of the holy writings can be used to justify almost anything we want. All we need is to pick and choose.
When some claim that the US is a Christian nation, again, we have to ask: what kind of Christian? There are old line churches such as the Episcopal or Presbyterian churches, the new line fundamentalist churches, and of course the oldest churches: the Roman Catholic and Greek Orthodox. They all interpret Jesus' teaching in a different way.
It appears that those who want religion in government are really saying that they want their religion in government. Just look what is happening at the Air Force Academy. Do we really want the USA to be as narrow minded and prejudiced as those academy bigots?
