I agree with Eugene Volokh when he observes that the Opus comic rejected by the Washington Post is pretty dang tame. I found the cartoon to be poking fun more at men and male attitudes than at Islam. I don't think there is any way the Post can argue now that their editorial policy is symmetric across all religions. They are tiptoeing around Islam in a way they never would with Judaism or Christianity. If they are scared of violent reprisals, they should just say so.
