Why do people deny the Holocaust happened?
"The Holocaust was a state secret in Nazi Germany. The Germans wrote down as little as possible. Most of the killing orders were verbal, particularly at the highest levels. Hitler's order to kill Jews was issued only on a need-to-know basis. The Nazi leaders generally avoided detailed planning of killing operations, preferring to proceed in a systematic but often improvised manner. The Germans destroyed most documentation that did exist before the end of the war. "
Holocaust denial has been called by some scholars the “new anti-Semitism" - What do they mean?
