There isn't a single swear word and no nudity or violence in this film and yet this is possibly the most disturbing and horrific piece of cinema I've ever witnessed.
Encapsulates everything that is wrong with fundamentalist religion, in this case Christianity. You will never witness a more wrenching hypocrisy than the female 'teacher' of the camp telling the kids that the enemy knows that kids are vulnerable and impressionable and that's why they're teaching them these things now to 'protect' them. Or the image of the parent dragging a toddler's arm into the air in response to a question that presumably required an affirmative answer in the parent's warped mind.
This film is essential (if somewhat stomach-churning) viewing in order to understand a part of American society that is becoming increasingly influential in decisions regarding the US's (already overly enthuastic) warmongering making these people potentially far more of a threat to world peace than the likes of the Taliban or Al-Qaeda could ever hope to be.
