Not at all. Charlie Hebdo are defending themselves against attacks from islamists - some violent.

They aren't defending themselves at all. They aren't attacked. They are disseminating standard mainstream anti-Muslim racism, and Muslims have no voice.

And that being also a defense of free speech should be supported

There is no freedom for hate speech. And even though this is not hate speech in the legal sense, it functions as hate speech, which is why I criticise Charlie Hebdo's despicable publication. I note that you categorise my speech as an attack on free speech: apparently only anti-Muslim speech is free.
