It says he draws Mohammed because violent bloodthirsty Muslims, befitting the way he draws Mohammed here, tell him not to. It is about not bowing to violent threats, and not encouraging more of them by letting them change our behaviour.
No, it isn't. Just like Pamela Geller's farce of a "contest" had jack shit to do with free speech. That was a ruse and a cover for her own poisonous bigotry, and that of her followers. Which is why it doesn't deserve praise or promotion, and certainly not from people who have the balls to label themselves "progressive."
And the same goes for this drawing, and the piece of shit who drew it. Please, go look at his other artwork, which portrays Muslims generally in the exact same manner, and the blog quotes I lifted, which clearly equates them with Nazis, and tell me with a straight face that the drawing is just about Muhammad.
And then tell me with a straight face that this is something that liberals ought to be not just praising, but promoting, raising the artist's public profile. And then tell me with the straight face that we'd even be having this discussion if it were a drawing of a black man or a Jew, and the artist were a known anti-Semite or racist.
If some crazy Jewish guy had try to shoot him for it, I would.
