This is one of the most amazing documentaries I have ever seen. It is sad, terrifying, and from a foreigner's perspective - one great reason not to live anywhere near Kansas.
No matter what you think of the Phelps' family though, one thing you have to agree: they stand up for what they believe in. What this documentary doesn't address is: why such a group can even exist in modern day society? They accuse all and sundry of being "fag-enablers". Basically any person or group (or country) who even vaguely supports homosexuality is off to hell. And that's what they proselytise. They don't hate those people - they just inform them that god hates them.
People accuse them of "hate crime" but the atheist reporter was given nearly a week's access and they were (nearly) all very pleasant and friendly to him. I found that remarkable.
His interviewing skills were brilliant. Very similar to our own Andrew Denton.
But back to the original question. How can such a group even exist? Well unfortunately the bible says everything the Phelps' preach. You cannot accuse them of hypocrisy on that front. So anyone who believes the bible also must accept the Phelps' position. It must be a terrible conflict for christians out there. Because those very US Christian values have "enabled" the Phelps family to exist. The US is a "Phelps enabler".
