Oh, sorry, I should have made my point clearer. This is that Holocaust deniers often say they are not antisemitic,just trying to be factual, but if you question them the right way, it turns out they are. What is really going on in their minds is that they mistakenly believe Jews are evil, and so they defend anyone who think the same, in this case the Nazis against the accusation of killing millions of Jews, even though they themselves think it would be great.
