Charlie Hebdo made fun of Islam. It poked fun at all religions, and it loved to ridicule extremists, but it didn’t shrink from antagonizing Muslims. In 2006, it reprinted Danish cartoons that mocked the prophet Mohammed. In 2011, it published a “Sharia” edition in which “guest editor” Mohammed promised “100 lashes if you don’t die of laughter.” A year later, the magazine depicted the prophet naked. On Wednesday morning, its Twitter account wished a happy, healthy new year to ISIS leader Abu Bakr al-Baghdadi.
