Irving isn't an anti-Semite (unlike some other Holocaust deniers like Ernst Zundel). He was just a man who thought he had discovered something important about the Second World War and wanted to revealed his findings to the world.
For this he has been besmirched and demonized. Anyone who tried to defend him from the accusation has been tarred with the same brush. This is not defending yourself from anti-semitism. It is witchhunting.
A British court found that he was. I'll ask you again, how did the Jewish conspiracy get to the judge?
