Hitler, Ahmadinejad - yes -- but who else?

Columbia University's School of International and Public Affairs (SIPA) invited , Iran's Holocaust-denying president to "participate in a question and answer session with university faculty and students at Columbia University’s World Leaders Forum."

Coatsworth stated that “Opportunities to hear, challenge, and learn from controversial speakers of different views are central to the education and training of students for citizenship in a shrinking and still dangerous world. This is especially true for SIPA students, many of whose careers will require them to confront human rights and security issues throughout the globe."

Since Coatsworth told the news invite Hitler to speak to and give him a platform - it seems almost pointless to ask if he'd invite Sudanese President Omar al-Bashirto, dictators like Robert Mugabe of Zimbabwe or Kim Jong-il of North korea or, for that matter, any of the rest of the world's top 10 worst dictators?
I don't think they would. But who knows....
