If a vegetarian eats vegetables, what does a humanitarian eat?

Vegetarians? Why isn't a vegetarian one who ONLY eats vegetables? There's some goofy other word for such a one. What sort of hood does an adult wear in adulthood? And, of course, there's the old infancy/adultery dichotomy. And, since "otomy" is a suffix used in medicine to describe the excision of something, why isn't a dichotomy the removeal of a dich?

If you've ever been to California, you've probably seen signs on major highways (which aren't always high) honoring the former Isreali Prime Minister. The signs say, "Begin Freeway."
