"I was born Christian. If that makes Rupert Murdoch my responsibility, I'll auto-communicate," Rowling tweeted in response to an earlier tweet in which the Australian American business magnate stated: "Maybe most Moslems peaceful, but until they recognize and destroy their growing jihadist cancer they must be held responsible."
Murdoch's tweet has been retweeted more than 6,000 times so far and marked as favorite by more than 3,000 people. It sparked a global outrage, mainly after being followed by another tweet: "Big jihadist danger looming everywhere from Philippines to Africa to Europe to US. Political correctness makes for denial and hypocrisy."
Rowling responded again, saying that "the Spanish Inquisition was my fault, as is all Christian fundamentalist violence. Oh, and Jim Bakker."
The British novelist was referring to remarks made by Bakker, an American televangelist, who said on New Year's Eve that God had come to him while he was taking a bath and told him that the US military would never win a war because Americans are "making it legal to murder babies, (taking) the Ten Commandments down and literally denying the words of God."
Rowling later added another tweet with the findings of a recent study, showing that "eight times more Muslims have been killed by so-called Islamic terrorists than non-Muslims."
Earlier, she praised Lassana Bathily, the Muslim worker at the Hyper Cacher kosher supermarket in eastern Paris, who helped six Jewish customers hide in the freezer rooms during Friday's terror attack, which left four Jewish hostages killed.
"The courageous and compassionate actions of Lassana Bathily remind us what 'humanity' ought to mean," Rowling tweeted.
