OK, the old Godwin’s Law observation with Ad Hitlerem is standard.  And we’ve here noted the Ad Stalinem.  But Glenn Beck just used, in his NYT interview, an analogy with Mao Tse-Tung with similar effect.

 I think these guys (progressives) are the biggest danger in the world. It’s the people like Mao, people that believe that big government is the answer, it always leads to millions dead — always.

For sure, Hitler analogies deserve their own name, but they are of a specific class of arguments by analogy roughly captured as the argument by analogy with some tyrant, so I’ve proposed Ad Tyrannem as the general class.

Oh, another irony is that not but a paragraph up from the implication that progressives will be putting people to death, Beck wishes that the American people could just get along.
