If the position that the holocaust never happened and/or is exaggerated is so silly, why not let deniers speak? Why not encourage them to make fools of themselves? Why not DEBATE THEM? That way you'll end doubting the holocaust forever and you'll expose how sick and truly antisemitic the deniers are? But if there is such a hue and cry every time someone publicly challenges the tenets of the holocaust, then obviously there's something to hide. The president of Columbia University called the holocaust the most documented event in history. Perhaps he is unaware that the judge in the Irving trial said he was truly surprised by the lack of documentary evidence, calling it extremely "thin." If there is so much misinformation about the holocaust, even by the president of an Ivy League school, then why can't these doubts be expressed? It's speech, folks. Hardly the same thing as, say, carpeting a nation with cluster bombs then refusing to tell the UN where those bombs were dropped.
