Actually, I remember watching the documentary Jesus Camp and there was a scene where the homeschooled kids recited an alternative version of the pledge of allegiance to the American flag, the Israeli flag and "the Christian flag." The last one was this one that is found in some American Protestant churches:
As an aside, this is a big pet peeve of mine about Evangelicals. The ridiculously over the top Israel love is annoying, bad theology (the resurrection is a thing guys!
), and ignores all the Arab Christians who have been screwed by all sides for the last few decades.
Edit: Just looked up the documentary. It's about Charismatics. There's your problem Indy.
