Take the following as truth: David Horowitz, right-wing firebrand and head of the Center for the Study of Popular Culture, has taken out an ad in six college newspapers excoriating tenured radicals for defending the distorted autobiographical writings of Guatemalan Nobel laureate and activist Rigoberta Menche.
Then the following statement: "David Horowitz is the pen name of Rigoberta Menche." is true, false, or inconclusive?
