The Holocaust was a horrible event, and one of THE darkest chapters in human history. As with many tragedies, different people have different reactions to the Holocaust. This includes outright denial that the event ever happened.
Even now, I still can't believe that some people try to claim that the Holocaust never happened. Have you ever seen the pictures or the real-life footage? Have you ever heard anecdotes from or met in person a Holocaust survivor? You cannot try to deny something that has definitely happened in the past, especially when there's clear evidence - and hoo boy, the evidence for the Holocaust happening is pretty damn clear. Sadly, holocaust deniers are all around the world. Personally, I don't know anyone who does deny the Holocaust (thank God), but I would be horrified if I knew someone who did.Bottom line:
Holocaust denial is retarded, because you cannot deny the definite past.^Throwing that out, because this is a sensitive topic.
