Conspiracy Theorists or Believers?

Joe Uscinski on reasoning with conspiracy theorists. (And I'm paraphrasing.)
"People like to imagine that reasoned dialogue changes minds. I'm not so sure. Lock a Jew and a Catholic in a closet for two hours and tell me that they'll come out with some compromise on their beliefs."
We call them conspiracy theorists but of course theories are subject to test and revision. Might be more honest to call them conspiracy believers.
