Conason's theory for the Sun's tirade

In Salon today Joe Conason speculates about the Sun’s recent editorial opposing freedom of speech for anti-war marchers:

I called Sun editor Seth Lipsky—a journalist with a good reputation who professes his devotion to “individual liberties”—to ask why he had published something so irresponsible and rabid. He writes most if not all of the Sun’s editorials, but he wouldn’t comment. Others say Lipsky was out of town last week and the author was managing editor Ira Stoll. (That sounds plausible. This is the kind of problem that arises when nobody is minding the store, and the idiot son takes over the cash register.)
