I'm not quite sure what your argument is. Are you arguing that anyone who kills an animal must take a perverse pleasure in it? Or are you saying that I take a perverse pleasure in it, but that someone else (from whom I would, per your second sentence, buy the meat from) doesn't? On what basis do you feel you can make either of those statements?
You're also overstating the cost involved... There are rabbits in my backyard. The ammunition costs a dime a piece. The rifle was inherited. You can't get meat much cheaper than that. (Certainly not rabbit.)
I don't know every hunter, but everyone that I know shoots paper or an animal that they eat. Why do you think most hunters kill animals and don't eat them? Do you have a source for that?
[Your sig is quite apt, also. Where are these shades of gray you refer to. Your world looks pretty black and white from here.]
