No legitimate cause can ever be advanced by denying the enormous human suffering caused by the massacre of millions of Jews and other minority groups by the Nazis. Attempts to use Holocaust denial as a political tool in the Middle East conflict will only serve to deepen the level of mistrust and hostility already present in the region.
Muslims are commanded in the Quran to "enjoin in the good and forbid the evil," and clearly the genocide of European Jews was nothing but evil. It is a shame that the current government of Iran, which claims to be an Islamic State, would ignore Islamic ethical values and belittle evil. Responsible governments must encourage the study of the Holocaust and other human atrocities to ensure that they are not repeated.
Americans in general and the Jewish and Muslim communities in particular should know that those who spew anti-Semitic bigotry do not speak for Islam; Muslims denounce their views and their hatred. Islam acknowledges Judaism (and Christianity) as a true revealed religion from God; furthermore Muslims view Jews (and Christians) as fellow "People of the Book" who believe in the same Abrahamic Monotheism.
While the cynical conference was held in Iran, it included many non-Muslim participants like former KKK leader David Duke and French "scholar" George Tail, who called the Holocaust a myth. The diverse participation is a reminder that bigotry is not exclusive to any one group.
As "People of the Book" we must stand united and challenge those who would fan the flames of all forms of hate, including anti-Semitism.
