McArdle--We don't care what you think you know about Glenn Greenwald. You have proof of sock-puppetry, besides his admission that a friend of his (boyfriend?) posted repeated praise of him without telling his connection to Greenwald? If not, drop dead.
You keep your mouth shut when it comes to answering his fact-based criticisms of you, except by making the most passive-aggressive, glancing responses possible. But you don't mind a little dig here, a little libel there. You don't have the brains, courage, or self-respect to challenge him openly, so you throw a little red meat to your more slimy commenters, in the hopes that they'll chew on it for a while and fling a lot of blood around.
