Wasn't there a TV Series in the 80's that had Lizards invading the World ? It was called "V" ?
Anyone who preaches or has the opinion that the Holocaust never happened is a total nutcase. My father is a holocaust survivor and I've heard some stories that are very hard to listen to. Even the memoirs of Rudolf Hess records the fine details of the running of Auschwitz concentration camp.
Sad to think people would follow this type of preaching without any truth or evidence.
