I was just looking at the topic of the child who was named Adolf Hitler by his parents who were non-Holocaust believers. I think it's utterly ridiculous to not believe in the holocaust because theres so much evidence for it. The only reason this is happening is that people can be so blinded by Anti-semitism (hate of Jews) that they would go so far as to say that there was no Holocaust, and say that all the pain, suffering, etc. those Jews went through was made up...that disgusts me, but i want to here others opinion, so elaborate...
There are generally 2 main theories when it comes to Holocaust denial:
Over the years Holocaust deniers have encompassed a wide range of beliefs. Paul Rassinier, the first well documented denier, was a French socialist who survived 2 German concentration camps, and was among the first to claim that the gas chambers did not exist - largely because he had not seen one. However his case generally retsed on his own conviction and he did little research to back up his claims. His general view was that it was a myth created by American and Jewish capitalists to help the birth of the state of Israel.
Right wing deniers on the other hand tend to believe that the Holocaust was a myth created to damn the Nazis. They stress that much of the evidence for the Holocaust comes from the USSR and that no record emnating from the USSR in the 1940s can be trusted.
It is conceivable that the USSR,'invented', the Holocaust for propaganda purposes.
However the case for deniers collapses because there is colossal evidence, not only from survivng Jews but also from the German perpetrators themselves, memoirs,eyewitness accounts, court testimonies, official government documents, that the Holocaust did indeed occur.
Personally, living in North London a (very Jewish area) I have come into contact with many survivors and heard what they have to say about it. To deny it is sheer foolishness, and an insult to those who were killed.
Not believing in the holocaust is utter stupidity. It's even worse than the ppeople who dont believe in the moon landing or the few that i've seen that believe 9/11 never really happened, we just used it as an excuse to attack the middle east.
