What should I ask Reza Aslan?

I will be doing a Conversation with him, here is Wikipedia:

Reza Aslan (Persian: رضا اصلان, IPA: [ˈɾezɒː æsˈlɒːn]; born May 3, 1972) is an Iranian-American scholar of sociology of religion, writer, and television host. A convert to evangelical Christianity from Shia Islam as a youth, Aslan eventually reverted to Islam but continued to write about Christianity. He has written four books on religion: No God but God: The Origins, Evolution, and Future of Islam, Beyond Fundamentalism: Confronting Religious Extremism in the Age of Globalization, Zealot: The Life and Times of Jesus of Nazareth, and God: A Human History.

And he has a new book coming, namely An American Martyr in Persia: The Epic Life and Tragic Death of Howard Baskerville.  So what should I ask him?
