Sort of related,
I watched a documentary called God's Cartoonist a few months ago. I was afraid it would be a "HA HA! Everybody make fun of Jack Chick!", but it came off as being fairly even handed look at people that could benefit from modern psychotherapy.
Jack doesn't appear on Camera because of all the Christians groups trying to kill him, but his main artist does, Kent Hovind, His researcher, One of his writers, the wife of another writer and a few people that are fans.
And it turns out the people behind Chick tracts are even nuttier than I imagined.
He met a guy named John Todd That told him the truth about the Illuminati. Who was later thrown in jail for rape. Except it wasn't rape, he was framed by Strom Thurmond.
And Alberto Rivera that told him the truth about the Catholics creating Islam to bring people closer to the Pope. He was poisoned by Jesuits that constantly rob his house. He died of the poisoning(The catholic doctors called it 'cancer') and the family buried it in an undisclosed location to keep the Jesuits from using his body in a ritual.
His last was Rebbecca Brown She ran an underground railroad rescuing people from the large satanic covens that infest the US and discovered things like yoga is a satanic plot to make it easier for demons to possess people.
His artist actually seemed like a decent fellow, but he wasn't interviewed too much.
