Let's talk about Holocaust

1. Do you believe in Holocaust?
2. Have you seen any proof that Holocaust happened?
3. Do you know that there does not exist a single document that would prove that Jews were killed in gas cameras during WWII?
4. Do you know that the official "witnesses" of the Holocaust have obvious discrepancies in their testimonies? For example, the Nazi driver Richard Beck testified that after the door to the gas chamber was opened, he could see bluish smoke over the corpses. But Hydrogen cyanide is colorless in gaseous form. Milton Bucki, a "Holocaust survivor", says that the corpses he saw had bluish skin color. But Hydrogen cyanide causes the skin to become reddish in color (due to prevention of gas exchange), not bluish. There are lots of factual inconsistencies in the reports about the supposed "Holocaust".

If Holocaust is such an undeniable fact of history, then why it Holocaust denial a crime in Europe? It's not a crime to deny Newton's laws or the Black Death in the Middle Ages, or the Crusades.
It's also not a crime to deny the casualties USSR suffered in WWII (which are much higher than the mythical 6 million that the Jews have been talking about for 30 years before WWII). So why are the Jews and their supposed Holocaust the Superior Race?
