What evidence is there that Ahamadinejad is racist?

I've heard this before, not sure if Ahmadinejad has changed his name and if he had a Jewish name before. I don't trust this guy Khazali, and since currently there are many rumors propagated by both his supporters and critics, I think we should wait to see what other sources would say about this. but based on what I've seen in years, he is racist. he intentionally or unintentionally is a big help to Zionism, giving them enough reasons to attack Iran and shut up their only critic country.
