JST would do well to study the way modern conspiracy theories develop, as I believe that the Jesus story is of that genre.
The typical motivation of any conspiracy theory is to shift the blame off whoever did something, and place the blame on the Jews or Masons. Hence Mohamed Atta was just a guy who was minding his own business, and Lee Harvey was really a great guy, and Pilate and his wife are saints. You can tell who really did it, by who the theorists are attempting to exonerate.
Typically, the theorist puts up a ridiculous, nasty theory, and then has to answer loads of criticism of it. They then develop counter arguments, and dig themselves in deeper, often manufacturing historical events, mysterious happenings, and a litany of witnesses that you can't interview, to support their delusions.
