This essay reconsiders the category of “Holocaust denial” as the marked indicator of ethical transgression in Holocaust historiography within American civil religion. It maintains that the present category excludes and thereby enables other violations of responsible Holocaust historiography. To demonstrate the nature and gravity of such violations, the essay engages the widespread claim that Hajj Muhammad Amin al-Husayni, the former mufti of Jerusalem, was an instigator, promoter, or “driving spirit” of the Nazi genocide against Jews, and the associated suggestions of (...) wider Arab and Muslim complicity. The essay uncovers the history of the Husayni narrative in question, the dramatic circumstances in which it emerged, its role in the 1961 trial of Adolf Eichmann, and its rediscovery and misuse within American popular and political circles over the past two decades. Such misuse, it concludes, corrodes Holocaust recognition within American civil religion and demonstrates the need for a revision of the socially accepted ethical boundary for responsible Holocaust historiography.
