This just in....Nerds are weird.
Nerds like Jerry Sandusky, who is as close to a typical example as any other pedophile.
The NSA screening procedure selects for controllable sociopaths with suppressed empathy of a fascist, Nazi turn of mind, the type that will follow an illegal order without batting an eye. The type that identifies masochistically to authority, the type that is sexually repressed and psychologically trapped in childhood frustration and Oedipal conflict that leads to homosexuality and pederasty. Gays make excellent spies and task masters, always have, particularly ones having to use guile and wit to remain in the closet.
