When someone talks about "conspiracy theorists" (in the propagandistic sense) concerning 9/11, I ask them if they believe 19 people "just so happened to hijack three planes and fly them into the same buildings by coincidence. When they say "no," I explain to them that they believe those 19 people got together with each other and the people giving them orders and they "conspired" to do that evil thing. So that person believes the "official conspiracy theory."
