Do you remember this movie from the early nineties? The comedian Sinbad starred as a genie named Shazaam in the movie, Shazaam! It was about two kids who summon that genie and ask that he grant them their wish, which was for their father to fall in love again.
Remember that film? Well, a lot of people do despite the fact that Sinbad never made a movie called Shazaam! Nobody did.
This article tells about folks who swear they saw this movie and when told it never existed would rather believe in a grand conspiracy theory than accept that their memories are faulty. They're probably remembering a movie called Kazaam which starred Shaquille O'Neal as a genie. (The article doesn't mention this possibility but some of them may also be recalling a 1967 Hanna-Barbera cartoon series called Shazzan.)
The amazing thing about this is not just the mass delusion but the stubborn insistence. Many years ago when I foolishly delved into the world of those who believed a conspiracy killed President Kennedy, I saw this. I met grown human beings who believed or at least would not rule out that maybe Martians had killed J.F.K. but thought you were a dupe (or more likely, part of the conspiracy) if you thought maybe — just maybe — that Oswald guy had done it.
Now, we have people who believe that some plot has erased all evidence of Sinbad's genie film and even pressured Sinbad into lying and saying he never made it. Somehow rounding up all those VHS copies that were sold or rentable at Blockbuster and purging all print media of mentions of Shazaam!…that's so much more logical than "Uh, maybe I was wrong." I leave it to you to draw the analogies to the election of Donald Trump.
