I was in the holy city of Varanasi and I saw what CNN showed the world on the new show Believer with Reza Aslan. I saw the Ganga, the holy river of the Hindus polluted.But It must also sting Hindu Americans that Aslan, an Iranian-American often called upon to speak out against stereotyping Islam, seems to be now playing a religious version of Fear Factor, the grimacing American gamely playing extreme sports in some dark continent.
