Nizkor is, perhaps, one of the most important holocaust sites around. It is unusually valuable in that it allows deniers (and other lunatics) a venue to spout their foolishness. The reason we feel this is so important is that it serves to remind us that people like Toronto's Ernst Zundel are not alone in their drive to misinform and hide the horror of the past. The biggest risk of recurrence rises from a lack of vigilance against deniers. The only way we can argue their statements is to know what they are saying. The only way to correct it is to face it.
