Your first assumption, that hunting is "killing for fun," is absurd. Even the hunting shows seen on TV ensure that the meat from their kills are donated to the poor or butchered and eaten by the hunters and families. Consider them "educational programs" for those of us who do hunt. I've hunted on and off for around 40 years,and haven't met ONE hunter who kills for fun, or for a trophy alone. Do some hunters display trophies? Sure! Do others display "trophies" of their accomplishments? Actors?(oscars) Sports champions? etc.? Everyone I know who hunts does so for the meat. I'm sure that the same anti-hunting crowd are screaming about GMOs in their food! Well!? Think about it! I would also submit that most hunters never fill their tag every year. I haven't! Yet, I enjoy the outdoors, the companionship of friends, the solitude, and, yes, even watching wildlife without taking a shot, which happens a lot, because not EVERY animal is legal to be hunted. Most hunters are responsible!
