Conspiracy theories
Here we go again. I've heard this all before. The illusion of politics. If any sane person believes this "mental illusion" then by the same criteria, and by using "optical illusion" theory, the existence of the 3 pronged fork drawn in 3D can be proven!!!!!!!
I just feel sorry for all those hundreds of folk in the auditorium being taken in hook , line and sinker. While there is definitely 1 sucker , I certainly hope the rest of the auditorium are not so naive to be taken in by such illusionary theories.
