Where are you getting that information?:hmm:
Ahmadinejad isn't an Arab; he's an Iranian. And before you get stereotypical on Middle-Easterners, we do not all look alike. You might also be interested to know that if you called an Arab an Iranian and an Iranian an Arab in the street, you'd be running from an angry mob in seconds. We don't like to be confused with one another.
The part about the Holocaust... I've never really known if he actually meant that or if he just said it to stir up trouble (kind of like Howard Stern with his jokes and what have you; he does it for publicity). Either way, it's a personal view, and although we know it's wrong, the majority of the Iranian people do not dislike Jews nor do they think the Holocaust never happened. The view of a single person does not constitute the view of an entire nation, no matter how powerful the person may be.
As for the rest of that post... just remember all Middle-Easterners aren't terrorists.
