Every once in a while the host of HBO’s Real Time with Bill Maher shelves his talking points to get at the truth. It doesn’t happen often, but when it does it serves as a tonic to his HBO audience expecting the standard anti-faith, anti-GOP rhetoric.

This week, Maher obliterated a guest who dared compare Islamic terror to crimes committed by Christians.

You know what — that’s liberal bullshit right there … they’re not as dangerous. I mean there’s only one faith, for example, that kills you or wants to kill you if you draw a bad cartoon of the prophet. There’s only one faith that kills you or wants to kill you if you renounce the faith. An ex-Muslim is a very dangerous thing. Talk to Salman Rushdie after the show about Christian versus Islam.

The guest in question, Brian Levin, serves as director of the Center for the Study of Hate and Extremism at CSU-San Bernardino. When Levin brought up Islamic terrorism critic Pamela Gellar to bolster his flailing case, Maher served up one more obvious truth.

As many people have pointed out — ‘The Book of Mormon,’ did you see the show? … OK, can you imagine if they did ‘The Book of Islam?’ Could they do that? There’s only one religion that threatens violence and carries it out for things like that. Could they do “The Book of Islam” on Broadway?

Levin offered a “possibly so” answer, proving his disconnect with reality is a palpable thing.
