I find this exchange interesting. It shows you that just like institutional anti-Semitism, holocaust denial is a Western Christian thing (not that some of those ideas can't be peddled by people in the region who receive them--but note the source): "That speaker, an Iranian historian, Gholamreza Vatandoust, from Shiraz University, said, “Some facts about the Holocaust have been documented.” But he was criticized immediately by Robert Faurisson, a French academic, who said he had never found documents to support the Holocaust."
