If you're going to change your menu or offer special items for people who have "religious-based" eating habits, you better darn well do it for someone who is morally and ethically opposed to the murder and torture of animals. Just because some ridiculous interpretation of a book written by men thousands of years ago says you can't eat certain things DOES NOT make your dining requests more weighted than those of a person who doesn't want to participate in the horrific treatment of animals. Religion is a choice, too. Either be considerate of all religious and ethical beliefs or ignore them all. I bring my own food to Thanksgiving every year, but I only go because my boyfriend wants to see his family. Seeing a dead animal cut up and consumed isn't exactly appetizing. A host providing veg(etari)an options is more of a compromise than a concession.
