Anyone ever says to me that I killed Bambi, I say "You know that Bambi was a cartoon, don't you?". Then if they don't feel dumb enough to shut it I'll ask if they usually have trouble telling the difference between cartoons and real life.
Also, when some a$$ that I don't know (thus don't mind insulting) says anything to me about hunting I usually tell them the following:
"I'm sure there are aspects of your lifestyle that would not appeal to me either, the difference is that I can mind my own business." If they give me lip, I'll go on to speculate what some of those things might be. I usually start with anal ### with multiple, anonymous men.... you get the idea.
