Author J.K. Rowling took to Twitter on Sunday to slam Rupert Murdoch for saying all Muslims “must be held responsible” for extremist violence such as last week’s deadly attack on the headquarters of satirical newspaper Charlie Hebdo.

On Friday, the News Corp boss said via Twitter that even peaceful Muslims are responsible for the “jihadist cancer.”

Maybe most Moslems peaceful, but until they recognize and destroy their growing jihadist cancer they must be held responsible.

On Sunday, the “Harry Potter” author linked to an article about Murdoch’s comments and unleashed a verbal stinging jinx:

I was born Christian. If that makes Rupert Murdoch my responsibility, I’ll auto-excommunicate. http://t.co/Atw1wNk8UX

She didn’t stop there. She also pointed out that the faith of her birth had a few flaws of its own and (sarcastically) took responsibility:

.@dom209 The Spanish Inquisition was my fault, as is all Christian fundamentalist violence. Oh, and Jim Bakker.

After the two zingers, she completed a Twitter hat trick by working some numbers into the argument:

.@peeyushmalhotra Eight times more Muslims have been killed by so-called Islamic terrorists than non-Muslims. http://t.co/JXLfZOmcKl

If Murdoch has seen the tweets, he hasn’t responded. However, on Sunday he tweeted in remembrance of a Muslim hero — and victim — in last week’s attack:

Extraordinary scenes in Paris today, but do not forget the heroic sacrifice of Ahmed Merabet, Muslim police officer whose funeral was today.
