Yes, it was an hoax. In even worse news, it appears as if the organizer of the Muslim "peace ring" is a virulent anti-Semite, 9/11 truther, a gay-basher, and an Israel-hater.
Ali Chishti, who organized the event, said bluntly in 2008, "I hate Jews and how they operate," reports Daniel Greenfield. Chishti added in his conspiracy-laden rant about the Jewish people, "It is a fact that during the attacks on the Twin Towers [World Trade Center] 1600 Jews were absent from work. OK, OK, what's even more suspicious, is how unusually many Jews there were present in Mumbai on the day that Pakistani terrorists struck. How come?"
At a March, 2008 meeting in Oslo promoting his 9/11 conspiracy theory that the Jews were responsible for the World Trade Center attacks, Chishti read his speech titled, "Therefore I Hate Jews And Gays," Haaretz reports.
