Why, today, do we hear so much about the Holocaust? Why are people we don't like called 'Nazis'? Why is Hitler's name constantly invoked as the embodiment of evil? Why is the Holocaust a perennial theme in films and documentaries? Why are there repeated references to "never again," "never forget," and the all-important "6 million Jews" who died?

And why, at the same time, is the topic of Holocaust apparently sacrosanct-literally off-limits to any kind of skeptical thinking or critical analysis?

Since the 1960s, the Holocaust has become an untouchable icon in Western society. And yet, so many details are murky: Why, exactly, did Hitler dislike the Jews? Did he actually issue an order to kill all the Jews? How did those infamous gas chambers actually work? And where did that number of "6 million" come from, anyway?

Lots of questions, very few answers-until now. Here, in this booklet, we attempt to address 100 of the most essential questions about the Holocaust, in an honest and forthright manner. As one of the most important historical events, it deserves no less.
