"We don't deny the Holocaust, but we believe the Holocaust was exaggerated by the Zionist movement to use as a whip."
"We don't deny the fact but we don't accept two issues. We don't accept the exaggeration of numbers and we don't accept that Israel uses this to do what it wants."
It's more dangerous than the hard core denial [e.g. the Holocaust never happened] because many people don't see it as denial but as "simply" a debate over the death toll which could be -- but in this case is not -- a legitimate historical debate over the death toll.
