For what it is worth, here are some of the images that got their creators murdered. Technically I suppose this puts me at risk but I seriously doubt I put my life in danger by publishing them. Even from this small selection you can see that Charlie Hebdo is an equal-opportunity offender. If you google them, you'll find absolutely spectacular Christian blasphemies, among other images, all offensive to someone I'm sure. Charlie Hebdo are in the tradition of French anti-clericalism, one of the moving spirits behind the French Revolution.
Remember, if you don't believe in freedom of speech for speech you don't like, you don't really believe in freedom of speech.
We must not allow the fanatics for whatever cause damage or limit our freedom.
We must not make excuses for them.
We must stand for what we believe.
