I have that to deal with at work sometimes. I have a good friend who is a Vegitarian, and he doesn't give me grief because he is inteligent. Most of the ones who give you grief arn't that bright. They usually spew some sort of prepackaged crap they heard at a PETA rally. I simply state my position. I am a human. we have clawed our way to the top of the food chain. I eat meat. I enjoy hunting. I enjoy my time in the woods. I am careful not to let them see the picture of the deer I killed last week ( my first ever) because I don't see any point in getting in their face. I basicly just let them know that I don't care what they think, and when they make some kind of retarded statement I calmly tell them they are misinformed. I had one lady at work who tries to start arguments say I would probly die from heart failure from clogged arteries. My cholesteral is 160. I run daily, lift weights several times a week, and she is a b lob with makeup and bad hair. I laughed at her. I have found that it's better to be calm and ignore some of the idiots.
When I was young there was a peta rally outside of a Burger King. They were miffed because they said the fish in the fish sandwiches there was from "non dolphin safe" nets. Me and some of my buddies went into burger king and bought a bunch of fish sandwiches and came out and ate them in the middle of their crowd. Almost started a riot. We were hoping they would come back soon, cause we were gonna set up a hibachi and grill some meet for them. I still think it's funny, but now I know better. Sometimes the path of least resistance is also the most fruitful.
