Yeah, from what I understand is that muslims in India eat mutton so they don't piss off their hindu counterparts. THe other meat besides mutton that they eat is water buffalo and not cow as cow is sacred to the hindus. If you go to INdian restaurants ant not Pakistani ones then you will see that they do not have any beef on their menu.
I've been to several restaurants in India that serve beef. It really isn't that difficult to find. And that includes non-Muslim/Christian restaurants.
If you go to Christian areas, we eat beef. I'm not talking about restaurants - I'm talking about where people actually live, as opposed to visit. Parts of Kerala, for example. It's not like people are scared to eat beef down there. Hell, if you have a wedding down there, cattle are going down.
