This thread is a marvelous showcase for how the human brain works. Let me explain it in simple terms.
If someone told me Elvis was alive, it wouldn't bother me in the slightest.
But if someone told me Elvis was alive and I responded by saying, "You think Elvis is alive? Seriously? You're crazy! Hey, Barney, this guy thinks Elvis is alive! We gotta tell everyone about this! Etc."
In the first case, it wouldn't bother me, because I know it's not true.
In the second case, my reaction indicates that a part of me ACTUALLY BELIEVES IT IS TRUE, and I'm experiencing such tremendous cognitive dissonance that it's causing a minor short circuit in my brain.
Posters obsessing over a dead guy are showing the world that a part of them believes he is dead, but it confilicts with the programming the media is feeding them. Hence, they don't know which way to turn. Rather than investigate the matter on their own, they lash out at the cause of their cognitive dissonance and double down on their programming.
