Who is more revolting?

Mahmoud Ahmadinejad with his shrewd obsession with linking the denial of the Holocaust to the Palestinian problem, or the motherfucker, vermin, lower and more disgusting than lice, ultraorthodox rabbis who are attending the Holocaust deniers' conference in Teheran?
Of course, Mahmoud hosts the conference and everybody around the world starts screaming: "it was true, it happened, the Nazis left all the records", which somehow to me, right as it is, is undignified. It is undignified to even answer or rebut these people. I know it needs to be done, just in case someone out there believes it, but I wish it didn't.
Now, people who call this Iranian conference on Holocaust denial "a sick joke" are wrong. Sick it is, but it is not a joke.

David Menashri of the Center for Iranian Studies at Tel Aviv University said Ahmadinejad's denial of the Holocaust was linked to his nuclear ambitions.

"Ahmadinejad's main concern today is to gain nuclear weapons for Iran. And somehow he believes that by raising the issues about Israel, wiping Israel out of the map, and denying the Holocaust, he will portray the image to countries like Germany and Europe that his main intention is against the Jews."

"He believes that if he is only against the Jews, then the world will be tolerant," Menashri said.

The spurious, sophistical argument Mahmoud raises, I've heard repeated by smart people in civilized circles, this conflation of why should the Palestinians pay for what the Jews suffered in WWII?
It is an easy jump to make, one that erases the political and historical context of an entire era, and it is an argument that needs to be countered forcefully, because its logic is that if the Holocaust is a fiction, Israel has no right or claim to existence.
The Palestinian problem must be solved, as I am now beyond exhausted from repeating, by the collective political will of many parties: Israel, the US, Europe, the Palestinians themselves, the terrorist groups who create chaos and division, and the Arab countries that do their utmost to prevent peace and stability from ever happening in the Middle East. It will not be solved by denying the Holocaust and scaring the shit out of the Jews with nuclear threats and vile antisemitism.
