I will remind you of something I've said before. Remember the background we all come from. Now tell me, wasn't this the biggest conspiracy theory we thought was actually the truth? Personaly I love the way the mind ticks and how even the smartest people can be duped into believing a lie.
Also I'm saying is let people be who they want to be, its not a nice thing to be labeled as crazy or suffering from bipolar. It's easy to slap a label on something we don't understand, that way the cognitive dissonance doesn't have to hurt us as much.
