Both positions have a reasonable side to them. Mattogno and Graf are not ready to dismiss numerous documents, and thus accept the deportation but not the killing. But Butz's position is eminently reasonable in a "revisionist" framework:
Graf accepts the 438,000 figure, but denies the killing. I also deny the killing of those who were deported, but I also deny the 438,000 figure or, more precisely, the idea that the May-July deportations virtually emptied Hungary of Jews, except for the Budapest area. I accept however that many Jews were deported in May-July 1944, mainly for labor. I cannot give a figure, but I believe it would have been only a fraction of 438,000. Graf cannot tell us what happened to most of the 438,000 Jews. Indeed the question that is the title of his paper remains begged.Indeed, selection for labor purposes explains the destiny of only about 100,000+ Hungarian Jews (more or less). What happened to the rest?
One cannot envy a "revisionist" - either she accepts the documents, but then cannot explain what happened to the Jews, and thus looks like a loony. Or she dismisses the documents and thus looks like a moonbat. Tough choice!
