HBO host Bill Maher debates guest Brian Levy, the director of the Center for the Study of Hate & Extremism at California State University in San Bernardino, about the Boston Marathon Bombers’ Muslim faith playing a role in their terrorism

“It’s not like people who are Muslim who do wacky things have a monopoly on it,” Levy claimed. “We have hypocrites across faiths, Jewish, Christian who say they’re out for God and end up doing not so nice things.”

Maher, true to form, called his guest out and said his premise was “liberal bullshit.”
