book, or eloping with the wrong person, not only does the muslim world have something in common with isis, it has too much in common with isis. reporter: aslam responds with an analogy from america. the christians at the westborough baptist church believes god hates homosexuals. as a result of that belief they picket the burial ceremonies of american soldiers who die overseas. now, christians in the united states also believe that homosexuality is a sin, so they share that belief with the westborough baptist church but would never share in those actions. by bill maher s logic, those two groups are essentially the same because they share one fundamental belief. reporter: sam harris, a critic of islam counters with his own american analogy. to have a play on broadway like the book of mormon it is currently unthinkable to produce such a play on the topic of islam. my name is jesus christ
