I do not think I offend non hunters by telling them I am a hunter. It is the antis that are offended.
I look at it like religon. If you are of a certain religon (christian, muslim or whatever)that is fine. Just don't try to push it on someone who does not want to hear it. Same goes for hunting. If they ask about it, tell them all about it. If they don't ask don't tell...Just my weird way to look at the world we live in.
