By the way, my wife informs me my brother-in-law is sucked in by loose change. She comes to me one day and says, "Have you seen this loose change web site?"
The average rational person can usually be dissuaded from falling for a conspiracy theory with one good question.
For the lunar landing hoax CT, it's, "If the government can't keep one guy's blowjob in the Oval Office a secret, how are they going to keep thousands and thousands of people from telling they took part in a lunar landing hoax going on more than 3 decades now?"
For the 9/11 CT, it's, "Where are the passengers of Flights 77 and 93?"
Anyone else is just too whacked to even bother talking to.
