Azor,

Do you know how the first openly gay linguist at the NSA was able to keep his security clearance?

"officials believed that a talented NSA linguist might be gay and stripped him of his security clearance, according to James Bamford, author of "The Puzzle Palace," a history of the code-breaking agency. But the linguist, represented by gay rights attorney Franklin E. Kameny, fought back. NSA Director Bobby Ray Inman agreed to a deal: The linguist could keep his job if he signed a document stating that he was gay, and if members of his family signed it, too, eliminating any possibility of blackmail."

Once information is open to the public, there is no longer a threat of blackmail. As long as personal information is withheld from the public ... well, you get the idea.
