There is nothing you can really say to try to persuade somebody who doesn't like the taste of meat to eat the next sloppy joe they see. That is the way it is with a lot of vegetarians. Some people switch to the veggie-life for health reasons. It is said that vegetarians live longer and have less of a chance of getting nastified diseases like heart disease, diabetes, and some types of cancer. These facts are because a vegetarian diet has less cholesterol and fat and more vitamins and fiber.
Many vegetarians are what they are because of a variety of religeous and ethical beliefs.
Some vegetarians such as Jains, Buddists, and Hindus, believe that killing and eating animals violates the ethical concept of ahimsa, or non-violence. Another reason why people become vegetarians is for animal rights. This act, in part says that an animal is supposed to be unconscious before killed. There are many faults in this act. For one thing, the act doesn't even consider chickens, turkeys, and other birds to be animals.
