What it does right: Fucking everything, it's message is subtle, and the reaction to it says more in terms of social commentary than the signs do. Other variants can be used, like "the Qur'an is right about women" or "the prophet Muhammad PBUH was right about women". Posting the sign in arabic near women's areas is another good move, and putting it on things that can be seen as representative of female degeneracy by arabs is also effective.
