The movie is not propaganda. Granted the documentary wasn't totally fair; they didn't do a great job showing two sides of the debate, despite having the talk show host guy giving differing opinions. I would have liked to have seen a Christian family (or families) interviewed who did not agree with the evangelicals seen in the film. But at the end of the day, very few documentaries are totally fair so that's not a good avenue for criticism.
Not every evangelical is as fanatical as the ones seen in the film but it would be naive to deny that millions of these people exist in this country, and they want to create their own particular "new world order". I've debated with evangelicals who feel all Muslims in this country should be deported, who feel homosexuals should be incarcerated in order to stop the spread of diseases, and who seem to glide over the first amendment as if it meant nothing. And many of them are some of the nicest people I've ever met, which is even more distressing about the whole affair.
At the root of this issue is church and state. If these people want to pray for George Bush by using a cut out that's fine with me. The line should be drawn when they attempt to push their religious beliefs into the public square by influencing our political system. I'm a Christian, and there are certain political issues that I don't apologize for mixing religion into - but when it comes down to using religion to segregate people or take away rights, a line is being crossed. That's dangerous, and Jesus Camp merely served as a glimpse into it.
