All behaviour is rational when you find its true root; moreover, it is only by establishing this true root that there is any hope of positive change.

The conspiracy theorist would rather hold a gun than form a trusting and loving bond. They find trust more scary than bullets. Hence their irrational behaviour is rational from that warped perspective. If you can show them that society can function, that they can form trusting bonds with others they view as "different" in some way, then you have a chance to reverse some societal decay.
