I simply would like to point out that, in my experience, it is the vegetarians who more often attack the meat eaters. I think the most derogatory term I have come across is "murderer". Those who do eat meat tend to offer info or encourage somebody to eat meat if they think that person may be lacking in something nutritionally, but if a veggie is trying to get someone else to stop eating meat, they can get very ugly and derogatory, and will question the person's morality and conscience - they get deep into judgement of the person as a human being because of their meat eating, and get very irate, insulting and impassioned. Ah, those ever-so peaceful and gentle vegetarians - I want to be JUST like them! :)
