What is your opinion regarding vegetarianism, and why do you feel that way?

I know humans are omnivores, so being a vegetarian is a bad choice to make. Many vegetarians are quite obnoxious. They act as if it is a religion that makes them superior to other people who know better than they do, and they are hostile and tyrannical, as are religious fundamentalists. It is distressing to see people who are so affected and unreasonable about such "gao pei".
