The motives of a researcher are irrelevant; only the results count. Likewise, any attempt to refute a revisionist book by attacking the – real or alleged – political beliefs of its author is untenable and impermissible from a scientific point of view. Even if all revisionists were staunch admirers of Adolf Hitler, this would not necessarily mean that their conclusions are wrong, just as the fact that most Holocaust historians are Jews does not prove that their theses are unfounded.
