To all the proponents of unlimited free speech - did you bother using your brains? Everybody sane knows the holocaust happened. And for the record - my father is a holocaust survivor. Claiming it did not happen (as well as the Armenian genocide, the Tutsi genocide in Rwanda, and the Darfur genocide, as well as several others) is meant as a rallying point for people that want to have yet another genocide - "Shame, Hitler did not finish the job". Should teachers in American schools teach that all Moslems want to kill non-moslems?
