the "unique" and liberal democracy

A recent column by Stanley Fish may help us think about the public use of the holocaust-it's meaning in to day's political world, its uses and abuses etc.
We often insist(rightly I would say),that the holocaust is unique and not to be compared to other atrocities in history. My friend Fackenheim argued strenuously that it should not be compared to the atrocities of racism, and rejects the pairing of the Holocaust and Hiroshima. This tradition of interpreting uniqueness of the Holocaust is so fixed on the incomparable that it seems to have lost its historicity ,as a catastrophe that blighted the earth we stand on.
But many who argue this way, including sometimes Fackenheim himself contradict themselves are ready to compare Arafat with Hitler and call many of Israel's adversaries Nazis
Moreover the success of our Holocaust institutions , the public commemorations of the Holocaust lie in the fact that it is seen as a paradigm of the evils of racismlinked to the experience of other peoples'
The dillemma is "if we insist on its uniqueness too stridently we say that the holocaust took place on another planet.
Fish's article is about a case where a religious group sought priveleges in enforcing its beliefs. Fish replied tat all religious groups
