I thought that those “other” religions were just prohibited from eating those things not looking at them! Sheesh During Lent I will sometimes go into a McDonald’s on a friday for their fish sandwich which I like very much. I am not offended that they are serving hamburgers there on a friday in Lent.
Muslims are indoctrinated that pigs are the "filthiest of animals". So, to a Muslim, pork is not just "forbidden", it's more like a Westerner would feel about people cooking rat meat in a shared kitchen, or rat meat sitting in the fridge next to your lunch.
