Bill Donohue, president of the conservative watchdog group the Catholic League, sparked outrage last week when he claimed that the twelve people killed in the attack on satirical French magazine Charlie Hebdo had brought it upon themselves by insulting Muslims.

Donohue's shock claim was denounced in the Washington Post and even by fellow conservatives, but the Catholic League leader has not backed down.

Doubling down on his claims at the weekend Donohue told Newsmax's Steve Malzberg that if an angry Christian were to kill artist Andres Serrano over his infamous "P-ss Christ" image, it would partially be Serrano's own fault.

"I don't mind Mel Brooks. I don't mind edginess. I don't even mind irreverence," Donohue said. "I do have a problem with toilet speech."

Artists have to stop producing "filth," Donohue said, adding that that while he would be opposed to someone killing Serrano for his work, it would certainly be Serrano's own fault if it happened.

"Had he exercised restraint, he wouldn't be dead," Donohue concluded.

Catholic League President Bill Donohue says if Christians kill over “P-ss Christ” images it would cartoonist own fault.
