When Jyllands-Posten published the now famous Mohammed cartoons back in 2005, I must admit I felt a bit annoyed. The Danish newspaper is consistently right-wing, so it was very fond of Dubya and his War on Terror, and it had no history of provoking people (other than left-wingers) just for the sake of it. I therefore thought their real motives had less to do with protecting free speech and more to do with provoking Moslems. At the same time, I supported their freedom of speech 100%. In other words, my attitude at the time was very well expressed by the quote wrongly attributed to Voltaire: "I disapprove of what you say, but I will defend to the death your right to say it."
However, this time it's different. Charlie Hebdo didn't just criticise Islam -- they were ruthless in their treatment of everything and everybody (see the cover illustrating this blog post), as a left-wing secular satirical magazine should. It would have been very strange for them not to criticise Islam using their best cartoonists from time to time. In other words, the terrorist massacre of Charlie Hebdo's core staff is the clearest attack on free speech imaginable, and we all have to join the fight against those people who want to transform our societies into illiberal, totalitarian regimes, whatever their religion and nationality.
Moi, je suis Charlie. Et toi?
