A few weeks ago, Charlie Hebdo cartoonist Renald Luzier, more popularly known as Luz, revealed that he would not be drawing Muhammad anymore. Soon after making this announcement, he also revealed that he is leaving the publication. His resignation will take effect this Septemer.

Luz became a Hall of Fame cartoonist when he put his portrayal of Muhammad on the cover of Charlie Hebdo in January. Just recently he called it quits: he pledged never to draw the Islamic prophet again, saying “it no longer interests me.”

The man is a coward, a bigot, a pornographer, and a liar.

Luz is a coward because he doesn’t have the guts to follow through on his 15 minutes of fame. He is a bigot because he delights in offending people of faith. He is a pornographer because much of his work has been patently obscene. And he is a liar because everyone knows why he really quit.

Had Luz been content to lampoon Muhammad in a conventional way, Bill Donohue would never have condemned him. But he had to get down and dirty and intentionally insult Muslims with his pornographic images. That is why Donohue jumped all over him. Now Donohue has lost respect for him again: he quit for the wrong reason.
