Bit late, but just to add: I am one of these unfortunate people who personally knows someone who denies the holocaust ever happened. To hold that veiwpoint infuriates me, and the argument that 'the Jews made it up' doesn't hold water, as there were millions of victims that weren't massacred because they were Jews, but because of other reasons. So that's more parties who would agree it happened, and it is not some great conspiracy.
