One afternoon this week, President Mahmoud Ahmadinejad of Iran addressed the United Nations General Assembly, once again casting doubt that the Holocaust had occurred. Almost exactly 24 hours earlier, an otherwise obscure college student in Morocco named Elmehdi Boudra was convening a conference devoted not to denying the Holocaust but to remembering it.

Mr. Ahmadinejad’s speech, not surprisingly, made major news around the world, as had his similar pronouncements in earlier years and his Tehran convention of Holocaust deniers. Mr. Boudra’s conference, meanwhile, attracted virtually no media attention of any kind.
