You don't get that either mate, eating Pork is haram in Islam if I m not wrong. How will a Muslim family feel then while sitting in a Pizza Hut when they'll see people on the next table feasting on 'Pizza Pepperoni'. Hindus got worked up bcz they thought those cattle were being taken to get butchered (which wasn't the case by the way) so if u justify that by any means then we have no right to question Muslims if they do same at a place which is serving Pork right ?
Muslims and Jews do not eat pork, they consider the animal dirty and unhealthy. When this rule was passsed many years ago, there may have been many illnesses associated with pig worms, pig viruses and food poisoning. Of course with better farming techniques and slaughter practices pork meat does not pose the same risks.
Muslims living in western countries routinely dine in places where meat such as pork, beef, chicken, mutton, fish is served. They will order either the halal or non-meat meals. You give the example of Pizza Hut, most Muslims will order the vegetarian and fish meals. The rest of the restaurant will be with people ordering what they want, pepperoni or not, it is not their business.
For Hindus the cow issue goes a lot further and seems to be a complicated affair, since a meat is a very expensive type of food and due to the scarcity, it seems that the early Hindus wanted to reserve the meat for the upper and warrior castes, obviously they need the protein to mantain body mass and muscle esp for fighting. However, for the rest of the population the cow was made a sacred animal. conferring the title mata joining the ranks of the mother and nature/earth as the other two mothers. To make the animal even more sacred and thus to protect it from hungry stomachs, the cow mata was said to contain the prescence of many millions of gods and goddesses and thus it cannot be eaten. Cow urine was promoted as healthy for human consumption.
Yet many Hindus and Sikhs do eat beef, just as many Muslims drink, just as many Jews eat pork, the realtionship with food is personal and depends on the individual. This type of mass pogroms over food over personal belief and this choice is simply a nonsense.
