The wacky President of Iran evidently is hosting a conference on Holocaust denial. It would be easy enough to write these people off as a bunch of nuts--which they are--but their host is openly trying to develop nuclear weapons capacity. Nuts with nukes can't be a good thing. Moreover, one has to wonder about the motivations of people to deny something that has been proven about as conclusively as any event in human history. The Iranians doubtless are cynically furthering an anti-Israeli political agenda, whether any of them actually believe this piffle or not. My guess is that some of the others simply hate Jews, and if they succeed in rewriting history (and thank goodness they won't), then they can justify whatever pogroms they have in their tiny little minds.
