Should vegetarians drink protein shakes

Protein shakes are doubtlessly of nutritional value to many vegetarians, but I would not say that all vegetarians should necessarily drink them, because there are various ways of obtaining a sufficient amount of protein in your diet without having to eat meat. For example, some vegetarians still eat dairy products (food made from milk) even though it is of animal origin; it is still not meat, and cows are not harmed by being milked. Cheese is very high in protein. Even for those vegetarians who do not eat dairy products, there are ways of combining carefully chosen vegetable foods in order to obtain usable protein. Tofu, made from soy beans, is also a good source of protein (not as good as cheese). But shakes are good.
