I don't know how I would react if confronted in that way. Maybe I would just be quiet and try to minimize the discomfort of the situation. Or then again I might really open up on them, which may not be good for the public perception of hunters. I would hope I would patiently explain that hunters are the tool of state game management which carefully stage hunting seasons and bag limits to maintain the game population at the appropriate levels. Without hunters, deer populations would expand excessively, causing damage to agriculture/gardens and increasing dangerous car collisions with people, as is the case in many northern states. I would perhaps explain that all game animals will die and the death they receive at the hands of a hunter is likely far more "humane" than the death they would otherwise receive in a harsh winter or run to ground by coyotes. Then again, I may be just as likely to just say "go &*^!@ yourself you decrepit old bag! Did I ask you to be my personal guru? How are you qualified to speak on this subject? What do you know about this topic?"
