I used to have the book from which this second-hand quote was taken, but I seem to remember it ran pretty close to this:
“Contrary to popular supposition, the KGB is not primarily interested in homosexuals because of their presumed susceptibility to blackmail.
“In its judgment, homosexuality often is accompanied by personality disorders that make the victim potentially unstable and vulnerable to adroit manipulation. It hunts the particular homosexual who, while more or less a functioning member of his society, is nevertheless subconsciously at war with it and himself.
“Compulsively driven into tortured relations that never gratify, he cannot escape awareness that he is different. Being different, he easily rationalizes that he is not morally bound by the mores, values, and allegiances that unite others in community and society. Moreover, he nurtures a dormant impulse to strike back at the society which he feels has conspired to make him a secret leper. To such a man, treason offers the weapon of retaliation.” — John Barron in KGB: The Secret Work of Soviet Secret Agents
There seems to be an unexplored (by the media) homosexuality angle to the recent Wikileaks controversy. If there is more to it, you probably won’t be hearing about it, so you can go ahead and forget about it now.
