"I'm not saying that governments don't lie, but a conspiracy like that would have to involve 100's of people. You can't hide something like that."
RESPONSE: "You're absolutely right. I agree with you 100%. It is impossible to totally cover up a conspiracy so massive. That's why I know about it! What you must understand is that they don't have to cover it up totally. Even a bucket that has a few leaks can still do the job of carrying water from here to there! They only need to fool 80% of the public, which isn't hard to do when you control the major networks and newspapers. The 10-20% that do figure it out (and the fewer still who will dare to speak their minds about it) can be very easily marginalized with the propaganda label "conspiracy theorist." The 80% + never take us critical thinkers seriously because they want to be part of the majority. This is known as groupthink. (*Note: When saying "conspiracy theorist", always hold your two hands up as you make sarcastic quote marks with your fingers.)
(The Ridicule Trick) "That's ridiculous (as he rolls his eyes). Do you really believe that nonsense?"
RESPONSE: "Can I ask you an honest question?" (Wait for "yes") Do you consider yourself an open minded, critical thinking person - yes or no? (Wait for "yes") Then how can you possibly ridicule an opinion when you haven't even done 10 minutes of research into the matter? That's kind of ignorant don't you think?" (Wait for response.)
"Not everything that happens in the world is a conspiracy!"
RESPONSE: "Not everything is a conspiracy, but nor is NOTHING a conspiracy either. Wouldn't you agree that we should evaluate each case independently and with an open mind?" (Wait for response.)
And so on.
