Iranian President Tests Limits of Free Speech in NYC

Ahmadinejad, at Columbia, Parries and Puzzles - New York Times

He said that there were no homosexuals in Iran — not one — and that the Nazi slaughter of six million Jews should not be treated as fact, but theory, and therefore open to debate and more research.
Mahmoud Ahmadinejad, the president of Iran, aired those and other bewildering thoughts in a two-hour verbal contest at Columbia University yesterday, providing some ammunition to people who said there was no point in inviting him to speak. Yet his appearance also offered evidence of why he is widely admired in the developing world for his defiance toward Western, especially American, power.
