The question here is less about beef eating & more about an attempt to openly provoke. These are the same chaps who accuse others of provoking communal outrage & then pretty much do the same thing. As pointed out, no one would do a "don't fast on Ramzan" festival, pork festival or even a cartoon drawing festival. These kinds of acts have an opposite effect than what many think, it will only serve to harden stands & create more resentment at such behaviour causing even moderate people who might not be buying into all this anti beef business into becoming more rigid because of the hypocrisy inherent in such acts.
That is for the state government to change it. All laws remain in existence (both India & Pakistan have laws dating to the colonial era) until changed.
