Prezniting is hard on paranoia.

Pachacutec from Firedoglake asks if this reminds us of anyone we know:
"A suspicious person is a person who has something on his mind. He looks at the world with fixed and preoccupying expectation, and he searches repetitively, and only, for confirmation of it. He will not be persuaded to abandon his suspicion or some plan of action based on it. On the contrary, he will pay no attention to rational arguments except to find in them some aspect or feature that actually confirms his original view. Anyone who tried to influence or persuade a suspicious person will not only fail, but also, unless he is sensible enough to abandon his efforts early, will, himself, become an object of the original suspicious idea."
